how to make a tree block--part three, sashings

Finished sashed block size is 8" by 9" (8 1/2 inches by 9 1/2 inches unfinished).
(Both blocks in the photograph are the same size--they don't look so partly because of my pressing, but also, there is an optical illusion caused by the colors.)

I make a block A and a block B so that when I put them together, there is no matching of seams between blocks.
Block A
Cut two pieces 2 inches by 6 1/2 inches to sew to sides.
Cut two pieces 2 inches by 8 1/2 inches to sew to top and bottom.
Press towards sashings.
Block B
Cut two pieces 2 inches by 5 1/2 inches to sew to top and bottom.
Cut two pieces 2 inches by 9 1/2 inches to sew to sides.
Press towards sashings.

Make half of the blocks A and half B, alternate them.

Next time: blocks of four.
