This amazing tape will eliminate drawing corner to corner on your fabric squares when you are making stitch and flip corners. Line your two fabrics up and feed the square into the machine on the diagonal following the bottom corner of the square in line with the center line on the tape. There are also lines that can be used as a 1/4" guide or if you wish to stitch the cut off corners together you would just use the left-hand solid line to make the stitch 1/2" away from the original diagonal. Cut in between the two sewn lines and you have the bonus Half Square Triangle unit as well. Watch for our video on this product! This tape has been tested and it has proven to stick better than washi tape-like products. Lisa had her original on her machine for over 6 months before giving it her stamp of approval. There are 7 strips per package and they can also be trimmed down if needed.
