Oh my gosh, I am reading this as I just got out of bed and drinking my first cup of coffee. Big, big mistake on my part. Head's still turning!!!!!!!!!!!! :-)

If you don't have acccess to an EQ, you can draw it out on a piece of graph paper. Figure the size your will need for each piece. Arrange these on a diagram of a 1/4 yd piece to see if they fit. If it is really close, you will need to allow a little extra in case the fabric does not come off the bolt straight.
Or you could buy 1/2 yard, cut it into FQ's and you will have some to swap or use as a gift.

Just a note to add - If you break it down, you need about 5/8 of a yard of each of 6 fabrics.

You can get 12, 9.5 inch squares from a 1 yard cut of fabric, 24 with 2 yards, plus another 1/3 yard. So 2 1/3 yards total. If your lqs will cut 9.5 to 10 wide 1/4 yard cuts, 2 1/4 would be enough.

4 fatt quarters in a yard.

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.

Lots of smart ladies on this board!

A fat quarter comes from dividing a half yard in two, split at the fold in the fabric. That gives you an 18 x 22" piece, instead of 9 x 44" piece, which may not work for what you want to do. Check the pattern to see if you need anything more than say, 8" in width...as most cuts at 1/4 yard are going to be off somewhere.

I'd get 3-3/4 yards (5/8 of a yard of the 6 colors needed). You may end up with little left over, but better than being a little short.

If you were to get 1/4 yard of 6 fabrics, you will probably have to do some piecing to make things work..and still may come up short.

i think your finger missed the key. how about 3.5?? smile...sounds likemy math. lol..
