Lisa - Thank you for that chart! It's going right into my reference binder!
MyTwoPals - I hadn't even taken bias into consideration!
Tippy- I hadn't thought of cutting paper templates....oh... I need a coffee so bad! So a 13" block cut in half from corner to corner will give me the big "what size?" triangle that I had drawn? - I am such a "visual" learner! Show me and I get it - tell me and I'll misunderstand you in 20 ways.... drives my family bonkers!
I'm glad I was able to calculate the small blocks for the 9Patch correctly! LOL! Did you ever have one of those days when you weren't just 100% confident in your skills? Today definitely qualifies! :)
