I think case, I would increase only the "outside" dimensions, so your end result is exactly what the pattern called for. How about this:


The 2 x 2 inch square cut 2 x 2 1/4. (Piece A)

The 2 x 3 1/2 inch rectangle don't change it. (Piece B)

The last piece 2 3/4 x 6 1/2 cut 3 x 7. (Piece C)

Sew the 2" side of A to B on each end. Then you should have a 7" piece that you can match to your C pieces.

But I'm with the poster above - if your blocks are coming out small, check your seam allowance and make it is smidge smaller.

If the block is coming out too small, there are a couple of things that might be happening:
1. you are not cutting accurately in the first place. Did you know that the ruler you use can make a difference? http://www.quiltingboard.com/main-f1...l-t142312.html

2. your seam allowance is too big. If you need help with achieving an accurate 1/4" seam allowance, I have a post here that might help: http://www.quiltingboard.com/tutoria...ce-t89997.html

I goofed! That's what I get for adding in my head and not double checking my numbers. As Krista said, the B piece should be 2x3-1/2 (don't know where I got 3-1/4!). Once you've added a square to each end, they will match up with a C piece cut 7" long, and you can then trim down to 6-1/2".

Sorry if my mistake confused you even further!
