After making potholders for a number of family members, I decided to make some for myself. I selected scraps in some of my favorite colors and sewed them in the "rail fence" pattern. Before I sewed the tops to the backing, I had to make sure the squares were square. For this I used my rotary cutter and square rule.
Next I sewed tops and backs together, leaving a small opening, laid the heat-resilient batting on top, and turned it all inside out. I blind-stitched the opening. Finally, I machine quilted on top, stitching "in the ditch" along the seam lines. All done!
