OK OMA66 - does that mean you became an Oma at 66?? from Holland?? My mom was Oma to my kids... I'm my grandkids' "Gus" ...that was my oldest Grandson's name for me - Oma was still around, Evan was 16mo old and couldnt say Gramms.
On another note...is there a formula for this method of HST?? I know if you do one block at a time you are supposed to add 7/8" to the finished size. It kindof looks like you need the diagonal measurement of the square plus 1/2" ??? [which would be the square root of twice the finished block size... calculators are good for this one...]
