You've heard of the Bermuda Triangle. But have you heard of the Perkiomen Valley?
The Perkiomen River valley is near where I live. Women there have been making Split Ninepatch quilts and setting them like this for over 100 years.
The pattern is called Perkiomen Valley Split Ninepatch. You might sometimes (rarely) see one in a show or in a book. I've made 3 of them and I have one bed sized one in the workroom closet now, waiting to be quilted. They were all the traditional Split Ninepatch quilt set this way. The traditional Perkiomen Valley Split 9Patch takes 100 blocks of 12 pieces each= 1200 pieces.
I recently started experimenting with old patterns and this was one of them. I just used plain triangles and sewed them into 4" HSTs with deep turquoise solid Kona cotton background and all different repro reds. This quilt took 100 HST blocks= 200 pieces.
It's 33" square. The deep turquoise "paths" are 2 1/2" wide. I plan on machine quilting it on my longarm, with continous curves on the reds and feathers on the turquoise.
