No problem Margo - glad it will help perhaps make the pattern more accurate - but as you say, with a little "give & take" on the block, it maybe didn't affect too many quilter's BOMs.
Sorry if I confused you re: printing my templates - it
wasn't that went off the page but, "margin settings" in my print program just prevented a few lines from being printed on the page, of one the triangles after I had to enlarge it by 4% to get the right scaling for my printer.
I have adjusted the 4 triangles (to right angles), drawn in the missing lines (next time I'll know to adjust the printer margins!) and cut the paper pieces and laid them out - and all looks great as far as accurately fitting - now if I can just finally decide which stash fabrics to use - it's a GO!
