Compare mattress sizes if you aren't sure how large the quilt should be.A jelly roll pack with 40 2-1/2" wide strips should make 13 to 16 quilt blocks, depending on how you position fabrics and whether or not all strips work with the design. That's 30 quilt blocks and a total of about 6-1/2 yards of fabric. A quilt with a layout that's five blocks across and six down finishes at about 70" x 84" (without borders).Each quilt block requires about 105 running inches of fabric, but keep in mind that you'll use multiple fabrics to create the blocks.The amount of each fabric needed depends on where that fabric will be positioned within the block and how many log cabin quilt blocks you intend to make. Bottom right illustration: Add dark pieces 8 and 9 to the quilt block, in the same manner, beginning with the shorter 2-1/2" x 8-1/2" strip on the left and finishing with the 2-1/2" x 10-1/2" strip on the top.Ĭalculating yardages for scrappy log cabin quilts isn't as precise as determining fabric requirements for an orderly quilt.Add the longer strip to the bottom and press. Sew the shorter strip to the block's right edge first. Bottom left illustration: Find pieces 6 and 7, a 2-1/2" x 6-1/2" light strip, and another light strip that measures 2-1/2" x 8-1/2".Refer to the block schematic as necessary. Notice that you're adding patches in a clockwise manner. Sew piece 5, a 2-1/2" x 6-1/2" dark strip, to the top edge of the growing block. Top right illustration: Find piece 4, a 2-1/2" x 4-1/2" dark strip, and sew it to the left edge of the block.Press all new seam allowances towards the newest strip.Sew piece 3, a 2-1/2" x 4-1/2" light strip, to the bottom of the red/light pair. Press seam allowance towards the red (or darker) square. Top left illustration: Sew the 2-1/2" light square to the right edge of the red square.Pressing to set seams before pressing to one side always improves accuracy. Pressing is less of a chore if you chain piece, but it's helpful for beginning quilters to sew a couple of individual log cabin quilt blocks first, to make sure construction steps aren't confusing.īe sure to sew with an accurate quarter-inch seam allowance. A standard or mini iron set up on a portable board next to your sewing makes pressing a cinch. Before you begin, be sure your ironing board and iron are handy, because log cabin quilt blocks have lots of seams that must be pressed.
