Thanks to all for the comments.
d.rickman~~you have a beautiful set of blocks, keep up the good work, love seeing them.
SheriR~~kudos to you for working on 2 at the same time. I struggle with doing one. WOW
Gus~~Thanks for the link to keep count of pieces used in each block or tri, but since I don't have excel on my computer, I have never been able to open any of those links. Guess I will muddle along and figure out my own spreadsheet. Thanks again.
