…especially for matching triangle points!
Have you ever tried it? At first I thought it would take more time but really NOT true. It actually went faster than any struggle for perfectly placed points I’ve had so far. Here are a few photos to show the steps.
Start by putting a dot of glue at the point on one side of the bottom piece to be joined, carefully place the top piece matching points, and place the hot iron on it to set. This only works if you set the school glue with heat.
I do trim my piece most of the time with this triangle quilt to be sure I have a 1/4″ seam.
