I have one set of templates and had another bigger set made by a local plastics company. I prefer to rotary cut my pieces. The die cut isn't economically possible at this time.
I was given a John Flynn set of Drunkard's Path and didn't like that the die cuts also cut into the seam allowances for the center marking. I have found finger pressing works great.
I only pin the halfway points and use angled tweezers to hold the far ends in place as I sew.
