Well, what do you know, I was looking through a box of stuff I "inherited" from another quilter and in it is an Easy Angle ruler! It measures 4 1/2" on two sides and ??? (didn't measure) on the hypotenuse side. Is this the ruler BH is using? Guess I'll try to make the HST using the ruler (if it is the correct one)! I got a D- in geometry (I think the teacher felt sorry for me and passed me even though he shouldn't have) and math has always been a struggle for me.
Eagerly awaiting the first clue. Going to Lowe's in the morning for the color cards and will try to get 4-5 extra sets to send out to those who need/want them.
Have a great evening!
