dotty- i have tried that method, but i don't know the formula to get the original square the right size. i think my major problem was seam allowance size. at that small there is no leeway. two threads off and you have a mess, especially when you multiply that by 5 in a 2" block. i think i will just start making bunches of little hst's and when i'm feeling more confident, and doing a better job, i will make a celebration mini, all hst's!
since the pattern called for squares sewn diagonallly and then the extra triangle cut off, i figured it was my chance to make even smaller hst's with the remnant. so... while they were stabilized i sewed another seam and cut the 2 hsts apart. itty bitty hst's. don't have a clue when or where i'll use them, but they are cute
