Here's my breakdown of the Patience Corner block using six fabrics:
Fabric Requirements for 25 9" finished blocks:
Fabric A – 5/8ths yard subcut into five 3-1/2” x WOF strips
Fabric B – 1/3 yard subcut into five 2” x WOF strips
Fabric C - 1/2 yard subcut into three 4-1/2” x WOF strips
Fabric D – 5/8ths yard subcut into five 3-1/2” x WOF strips
Fabric E – 1/3 yard subcut into five 2” x WOF strips
Fabric F - 1/2 yard subcut into three 4-1/2” x WOF strips
Step 1: To make the first two sections of the 9" block, strip piece strips sets of five 3-1/2" x WOF strips of A and five 2" x WOF strips of B. Subcut that into 3-1/2" pieces. You get about 11 pieces 3-1/2" x 4-1/2" from each strip set or fifty-five 3-1/2” x 4-1/2” subblocks.
Step 2: Cut three strips of fabric C 4-1/2" x WOF. Subcut that into 2" by 4-1/2" pieces. You will get about 20 from each strip or 60 total. Sew one C strip to each 3-1/2: x 4-1/2” block from step 1 – each sub-block should look like Unit 1.
Step 3: strip piece strips sets from five 3-1/2" x WOF strips of D and five 2" x WOF strips of E. Sub-cut that into 3-1/2" pieces. You get about 11 pieces 3-1/2" x 4-1/2" from each strip set or fifty-five 3-1/2” x 4-1/2” sub-blocks.
Step 2: Cut three strips 4-1/2" x WOF of fabric F. Sub-cut that into 2" by 4-1/2" pieces. You will get about 20 from each strip or 60 total. Sew one F strip to each 3-1/2: x 4-1/2” block from step 3 – each sub-block should look like Unit 2.
