I found this potholder pattern online...had to use internet archives wayback machine since the original site it was on is no longer available. I hope this link works , the picture of the potholder no longer shows. (This is the pattern for the potholder I showed in my previous post and the same one I put in the frame)
I made a couple of changes since some of the pattern didn't make sense to me..LOL. on Round 9 I ended up just evenly spacing the 13 shells around. I think Round 11 and round 16 are not clear or have mis prints also so I just adapted.
