Hi everyone! I am done with Clue 1 and Clue 2. I am having a problem with Clue 3. When I cut a 2 x 5" piece, and add a side piece using my Corner Clipper Ruler at 2", I am coming out with a 2 x 4 1/2" piece, which makes sense since I am sewing 2 of the triangles onto the 2 x 5". According to Bonnie's instructions, each unit should be 2 x 5" before being sewn into the quilt. Where am I going wrong here??? Help!
