I have made two quilts with a 7” DP block, and I have one with a 4” DP block ready to sew together (all the DP blocks are done). I also have done one with a modified 8” DP block called circle in a square.. The best hint I can give is to look at an old video by Ebony Love about Drunkard’s Path without pins. It really works, is faster, and it is quite accurate. If you don’t have a die cutter, just crease the center of each piece for matching. You sew with the big piece on the bottom and the small piece on top. It works, it really does! Note the bigger the diameter of the circular part the easier it is to sew. I would not recommend a 3 or 4” block as your first one!
