...when it comes to making hundred's of half square triangles, lack of accuracy will get you everytime. It sure did for me. As mentioned in my previous post, this UFO goes back 4 years. Dozens upon dozens of HST's were made according to the instructions...I knew better...why I did not use Triangles On A Roll (TOAR) at the beginning, escapes me. Cutting many, many individual triangles can often lead to disaster when piecing and needing a 2 1/2" unfinished square.
Take a close look at the difference...
First ones made piecing two triangles together....Just a bit off wouldn't you say?
Brand new HST's...spot on...using TOAR
Then when sewing each HST to the next, needle position gets moved one dot to the right of center and on goes #57 - 1/4" foot with guide.
Works for me and lesson learned. Now back to joining those rows together...
What do you do to ensure good results when piecing?
