Well..I haven't made any of these blocks yet....but I know that a "scant" 1/4 in. is prob'ly
necessary.....my own rule is to measure, measure, and check again !! I know that the single
rows/units have to finish at 6 1/2 inches. Cutting pieces from templates does add that
obnoxious pencil line ! And when printing the they need to measure correctly....# 1 is a 2 1/2 in.
square ...if it doesn't measure that , then you need to check the printer settings. No
scaleing and print to actual size setting. The % on the PDF shouldn't matter...maybe yours is different, though.
I s'pose that's clear as mud !
