hey folks did some searching on this site and through some friends this is what I have found.
Counted up the sashings that go between the blocks, I got 31 strips @ 2.5" wide with 1/4" inseam, length will depend on the size of your block once you've squared it up.
You will need to cut 20 of colour B @ 2.5" square to put at the end of the sashings.
I'm guessing these are the blocks for the four corners of the borders.
Corner pieced blocks for border (6 1/2" squares)
4 brown and cream 6.5" blocks:
4 cream 2.5" squares
16 cream triangles made from one diagonal cut of eight 2 7/8" squares
16 brown triangles made from one diagonal cut of eight 2 7/8" squares
4 brown check and cream 6.5" blocks:
4 cream 2.5" squares
16 cream triangles made from one diagonal cut of eight 2 7/8" squares
16 brown check triangles made from one diagonal cut of eight 2 7/8" squares
copied these 6.5" blocks from a chat I found on this blog site. Where the finished blocks are to be 6.5" then the borders should be 7" wide to allow for the 1/4" seams.
I'm really hoping this will work out - best of luck everyone. I'm going to start cutting these measurements out today
