How to Make a Quilt: Preparing Fabric for Quilting

• you are creating a quilt with a distinct design that will lie flat, as in a wall hanging, bed quilt, or table runner. Quilting fabrics may shrink in the wash, creating puckers or wrinkles that will distract from precise geometric patterns.
   
• you are using dark colors that may bleed in the wash. Bright reds, dark blues, and hot pinks are likely to bleed, so you will want to check these fabrics for colorfastness before using them in a quilt that will be washed often.
   
• you are sensitive to chemicals or dyes. Many commercial fabrics are treated with chemicals and artificial dyes, so you will want to prewash quilting fabric before working with it if you are concerned about an allergic reaction.

• you want to achieve the crinkly look and feel of a quilt that has been worn in and washed frequently. If you wash the quilt after it is finished, it will pucker and crinkle as it shrinks, changing the texture and appearance of the quilt top. Many quilters feel this gives their quilts an antique or vintage look.
   
• your finished project is purely decorative. If you do not anticipate laundering the quilt, you should not have to worry about dyes bleeding or fabric shrinking in the wash.
   
• you have just enough fabric. I have found that some fabrics unravel a bit in the wash. This is a minor issue when you are preparing a yard or more of fabric, but fat quarters and smaller pieces may come out quite a bit shorter than they went in.
  If you look closely at the photo below, you can see the tangled snags of thread on the edges that used to be another quarter inch of fabric:

Whether you prewash your fabrics or not, the next step in learning how to make a quilt is getting in the habit of pressing your fabrics before cutting. When it comes to fabric preparation, this is a very important step. Wrinkles and creases interfere with precise cutting and pinning, so it is important to iron your fabric flat before starting your quilt.

Haul out your ironing board, heat up your iron, and press each piece of fabric until it is smooth and even. Once you have ironed your fabric, lay it open on a flat surface until you are ready to cut to prevent any new creases from forming.
