I am referring to Wild nWooly in Greeley. Right now the lady who teaches the classes is apparently ill. They have my email address and will contact me when she is ready to teach again.
When we lived in the Denver area a few years ago, there was a great quilt shop on East Hampden, around I believe it was Tamarac. Don't know if it is still there or not, or even if they give quilting classes. It was sure a great shop though. My mother-in-law would always have me take her there when she came to town.
Hope I spelled the shop in Greeley correctly.
