Four-Patch Quilt Blocks Strip Piecing Tutorial | New Quilters

When you want to make a lot of four-patch quilt blocks from the same two fabrics, strip piecing is the way to go. It’s fast, it’s accurate, and it’s easy. It’s also a good way to make use of a precut jelly roll of 2-1/2″ strips. Here’s an illustrated guide to strip piecing a set of four-patch blocks.

You’ll need a set of four fabric strips cut from the two fabrics you want to use to make the blocks. One set of strips should be darker, and the other one lighter, to give the finished block its distinctive checkerboard look.

 Step by Step Instructions

  1. Lay the light and dark strips with right sides together, like this:Strip Piece Four-Patch Quilt Blocks
  2. Sew with a scant ¼” seam along one long side of the paired strips. You’ll notice that I mark the 1/4″ mark on my sewing machine with blue painter’s tape. This really increases the accuracy of my piecing. Try it! Four-Patch Quilt Block sew strips on one side
  3. Press the seam to the side with the darker fabric. Pressing to the darker side keeps the seam allowance from showing through the quilt top when you’re finished. Four Patch Quilt Block press unit open

  5. Use a rotary cutter and a cutting ruler to cross-cut the strips into units the same width as the fabric strips you started with. If your original strips were 2½”, for example, cut the strips into 2½” units.

  6. Sew the two units together alone one of the long sides. You may want to use a bamboo skewer or a stiletto to keep the seam allowance from getting folded the wrong way under your machine’s feed dogs. Four-Patch Quilt Block Sew Units Together
