Easy Guide Quilter's Math to calculate unfinished base units (with 1/4" seam allowances) based on finished unit: 1)Squares or rectangles add 1/2" (for 4" finished square cut @ 4 1/2" unfinished square; 2) Half-Square Triangles add 7/8" (for each 4" finished HST cut (2) @ 4 7/8" unfinished squares); 3)Quarter-Square Triangle add 1 1/4" (for each 4" finished QST cut (2) @ 5 1/4" squares).

This seems so obvious now that I see it. Clever way to trim HST to correct size BEFORE pressing them open.

Fun quilt block. On my to-do list.--I've got the pattern book for this, but have never made.  Very pretty here and easy too see all broken down.
