However, most patterns advise drawing a line along the stitching line before sewing. That can become tedious quickly when you have a lot of sections to piece. Many quilters are tempted to skip it, often with undesirable results.
Clever quilters use tape (or cardboard) instead. It’s quicker and, with careful “steering”, can be just as accurate.
Allison from Cluck Cluck Sew shows one method for using this time-saving method. Her article goes on to explain the full stitch-and-flip process.
This method can also be used for making two half-square triangles (HSTs) from two squares of fabric. You’ll want to position the tape a little differently than in the example above and mark guidelines.
Once the tape is in place you can use it for stitch-and-flip also. Notice how the tape goes nearly to the feed dogs for optimal accuracy.
The HST process is explained in an article from April Rosenthal.
Donna Amos uses a strip of cardboard for HSTs and stitch-and-flip. She lays it on top of the pieces to serve as a guideline for sewing.
Clever, and it may have other uses that we haven’t discovered yet.
