I just read an amazing thing on the 'picture' section under 'podunk' project. Windows ten adjusts all the FW sampler quit patterns (probably later patterns in in the series of FW) and causes the blocks to come up short both in templates and paper piecing. Wow! Instead of using PDF files, go through Acrobat Reader and it prints them out the right size. We all adjusted in our seams, I am sure but that was an eye opener for sure.
