Thank you all so much for your input. Overnight i have thought about it and gotten a different perspective. I'm going to one more class and the next block has HST in the block and i know that it will be challenging for the other quilters so i want to ssee if she muddles through it or actually teaches. I'm always looking for different ways to do HST's for better accuracy. The add 7/8 and the three dudes way i have found to be best for me. Maybe she has a better way.
