- Determine fabric length.
- Add extra fabric for borders.
- Check for fabric patterns.
- Double-check calculations.
By following these points, you'll ensure that your quilt backing is the perfect size and complements your quilt top beautifully.
Measure quilt top accurately.
Measuring the quilt top accurately is the foundation for calculating the backing fabric. Here's a step-by-step guide to ensure precise measurements:
1. Prepare your quilt top: Lay the quilt top flat on a large surface, ensuring it's smooth and free of wrinkles.
2. Choose the right measuring tool: Use a high-quality measuring tape, preferably one designed for quilting or sewing. A metal or fiberglass tape measure is recommended for its durability and accuracy.
3. Measure the width: Place the measuring tape along the widest part of the quilt top, from one side to the other. Record this measurement.
4. Measure the length: Next, measure the quilt top's length, from top to bottom. Again, record this measurement.
Double-check your measurements by measuring the quilt top in different directions and comparing the results. Accurate measurements will ensure that your backing fabric fits perfectly and creates a seamless quilt.
Consider seam allowances.
Seam allowances are essential in quilt making as they provide extra fabric for stitching and joining the quilt pieces. When calculating the backing fabric, you need to take seam allowances into account to ensure that the backing is large enough to accommodate the entire quilt top with seam allowances.
-
Standard seam allowance:
The standard seam allowance in quilting is typically 1/4 inch (0.6 cm). This means that you'll need to add 1/2 inch (1.2 cm) to both the width and length of your quilt top measurement to account for the seam allowances on both sides.
-
Adjusting seam allowances:
In some cases, you may need to adjust the seam allowance. For example, if you're using a bulky fabric or if you want to create a wider seam for a specific design element, you can increase the seam allowance to 3/8 inch (1 cm) or 1/2 inch (1.2 cm).
-
Calculating with seam allowances:
Once you've determined the seam allowance, add twice the seam allowance to both the width and length measurements of your quilt top. This will give you the total width and length of fabric you need for the backing.
-
Double-checking:
Remember to double-check your calculations, especially if you're adjusting the seam allowance. It's better to have a slightly larger backing fabric than a smaller one that won't cover the quilt top properly.
By considering seam allowances and adding them to your quilt top measurements, you'll ensure that the backing fabric is the perfect size for your quilt.
Choose suitable backing fabric.
The choice of backing fabric is crucial for the durability, appearance, and overall quality of your quilt. Here are some factors to consider when selecting the backing fabric:
1. Fabric weight and drape: Choose a backing fabric that is similar in weight and drape to the quilt top fabric. A lightweight backing fabric will pair well with a lightweight quilt top, while a heavier backing fabric will provide more structure and support for a heavier quilt top.
2. Fabric content: Consider the fiber content of the backing fabric. Natural fibers like cotton and linen are breathable and absorbent, making them a good choice for quilts that will be used frequently. Synthetic fibers like polyester and nylon are durable and wrinkle-resistant, making them suitable for quilts that will be used less often or need to be washed frequently.
3. Color and pattern: The backing fabric should complement the quilt top fabric in terms of color and pattern. You can choose a backing fabric that matches the quilt top fabric, or you can use a contrasting fabric to create a unique and eye-catching design.
4. Special considerations: If you're making a quilt that will be used by children or babies, choose a backing fabric that is soft and gentle on the skin. If you're making a quilt that will be used outdoors, choose a backing fabric that is water-resistant or waterproof.
By carefully selecting the backing fabric, you can create a quilt that is both beautiful and functional, and that will last for years to come.
Calculate fabric width.
Once you have chosen a suitable backing fabric, you need to calculate the width of fabric required. Here are the steps involved:
-
Measure the quilt top width:
Using a measuring tape, measure the width of the quilt top, from one side to the other. Record this measurement.
-
Add seam allowances:
Add twice the seam allowance to the quilt top width. For example, if you are using a 1/4 inch (0.6 cm) seam allowance, you would add 1/2 inch (1.2 cm) to the quilt top width.
-
Divide by fabric width:
Divide the total width (quilt top width + seam allowances) by the width of the backing fabric. This will give you the number of fabric widths needed.
-
Round up to the nearest whole number:
Since you can't buy a fraction of a fabric width, round up the result to the nearest whole number. This will ensure that you have enough fabric to cover the entire quilt top.
For example, if your quilt top is 60 inches wide, you would add 1/2 inch for seam allowances, giving you a total width of 60.5 inches. If the backing fabric is 44 inches wide, you would divide 60.5 by 44, which gives you 1.375. Rounding up to the nearest whole number, you would need 2 widths of backing fabric.
Determine fabric length.
Once you know the fabric width, you can calculate the length of fabric required for the backing. Here are the steps involved:
1. Measure the quilt top length: Using a measuring tape, measure the length of the quilt top, from top to bottom. Record this measurement.
2. Add seam allowances: Add twice the seam allowance to the quilt top length. For example, if you are using a 1/4 inch (0.6 cm) seam allowance, you would add 1/2 inch (1.2 cm) to the quilt top length.
3. Add extra fabric for borders (optional): If you plan to add borders to your quilt, you need to add extra fabric for them. The amount of extra fabric depends on the width of the borders. For example, if you want to add a 3-inch border on all four sides, you would add 12 inches (3 inches x 4 sides) to the quilt top length.
4. Calculate fabric length: Add the quilt top length (with seam allowances and borders, if applicable) to the length of the backing fabric selvage. The selvage is the finished edge of the fabric, which is typically 1-2 inches wide. Adding the selvage ensures that you have enough fabric to cover the entire quilt top and allow for easy sewing.
For example, if your quilt top is 60 inches long, you would add 1/2 inch for seam allowances and 12 inches for borders, giving you a total length of 72.5 inches. If the backing fabric selvage is 1 inch wide, you would add 1 inch to the length, giving you a total fabric length of 73.5 inches.
Add extra fabric for borders.
Borders are a great way to add a decorative touch to your quilt and frame the quilt top beautifully. If you plan to add borders to your quilt, you need to calculate how much extra fabric you need to purchase for the backing.
1. Determine the border width: Decide on the width of the borders you want to add. Common border widths range from 2 inches to 6 inches, but you can choose any width that you like.
2. Calculate the total border length: To calculate the total border length, multiply the border width by 4 (for all four sides of the quilt). For example, if you want to add a 3-inch border, the total border length would be 3 inches x 4 sides = 12 inches.
3. Add the border length to the quilt top length: Add the total border length to the length of the quilt top, including seam allowances. This will give you the total length of fabric you need for the backing, including the borders.
For example, if your quilt top is 60 inches long and you want to add a 3-inch border, the total length of fabric you need for the backing would be 60 inches (quilt top length) + 1/2 inch (seam allowances) + 12 inches (border length) = 72.5 inches.
Check for fabric patterns.
If you are using a patterned fabric for the backing, you need to check the pattern carefully to ensure that it will look good on the quilt. Here are a few things to consider:
1. Pattern scale: Pay attention to the scale of the pattern. A large-scale pattern may not be suitable for a small quilt, while a small-scale pattern may get lost on a large quilt.
2. Pattern direction: Some patterns have a specific direction, such as a floral pattern with flowers facing a certain way. Make sure that the pattern is oriented correctly on the backing fabric.
3. Pattern placement: Consider how the pattern will be placed on the backing. Will the pattern be centered, or will it be offset? You may need to purchase extra fabric to ensure that the pattern is placed correctly.
4. Pattern matching: If you are using a patterned fabric with a repeat, you need to make sure that the pattern matches at the seams. This can be challenging, especially if the pattern is large or complex.
If you are unsure about how the pattern will look on the quilt, it's a good idea to make a sample quilt block using the backing fabric. This will help you to see how the pattern looks in different orientations and how it matches at the seams.
Double-check calculations.
Once you have calculated the amount of fabric you need for the backing, it's important to double-check your calculations to ensure that they are accurate. Here are a few tips:
1. Review your measurements: Make sure that you have accurately measured the quilt top width and length, as well as the fabric width and length. Even a small error in measurement can lead to a significant difference in the amount of fabric you need.
2. Check your calculations: Go through your calculations step by step to ensure that you have added and subtracted correctly. It's easy to make a mistake, especially if you are working with large numbers.
3. Use a calculator: If you are not confident in your math skills, use a calculator to help you with the calculations. This will reduce the risk of making a mistake.
4. Ask for a second opinion: If you are still unsure about your calculations, ask a friend or family member to check them for you. A fresh pair of eyes may be able to spot an error that you missed.
Double-checking your calculations is an important step in ensuring that you have the right amount of fabric for the backing. It's better to take a few extra minutes to check your work than to end up with too little or too much fabric.
