I'm new at posting a new thread so please bare with me. Want to make a "mountain" quilt for my daughter and her husband. The technique is easy; use 8" triangles and cut them from left 2 1/2" (1st cut) 2 1/2" (second cut) final cut 2 5/8". You get mirro images when you layer 2 triangle sqs. the correct way. My problem is the highest peaks do not match up. They are about 1/4" off-set. Does someone know what exatcly I'm doing wrong? I always make a sample block prior to cutting all my blocks. Thanks for any imput.
