I'm working on a wallhanging. I checked my block measurements as I made them. They were off; I admit that. I foolishly chose to carry on. I added the sashing thinking I could correct the mistake but it couldn't be done. So I took the outer sashing pieces off and redid one of the offending blocks. That solved most of the problem. The center should be 22 1/2" square. Once I did the above and squared up the center I'm at 20" square - give or take. When I measured through the center for my vertical inner border it was 20". But my horizontal measure ment was 19.75 (if I'm reading the measurement correctly) I need to get to 22 1/2 because the outer border is made of up HSTs (I've already made them) and I don't want to cut any of them down if possible. Here is my idea:
Make a new outer border. The vertical strips would be
2 1/2" wide and the horizontal strips would be 2 3/4" wide. Then the outer border would be the HSTs and they should fit exactly. I'm hoping.
Does that make sense? Or would that 1/4" difference in width throw it off again. Is there a better way to correct this?

Your solution makes perfect sense to me, but I'd cut all the strips 3" wide, put them on as usual and then trim your piece to 22½" square using the center of the inner pattern to line it all up.
The extra width of the strips will protect you from having to do again should anything be off by 'just a touch'. The tiny difference in border with on two sides will never be noticed at all.

Let me see if I can help you, if I understand your question.
You have a block that is 20" h by 19 3/4 w. You need it to be 22 1/2 " square. Right?
Remember with each seam, you lose 1/2" -- 1/4" per square/strip.
So, for top and bottom, you need 2 strips, 1 3/4" each. 20" + 1 3/4 + 1 3/4" = 23 1/2" minus 1" for seams = 22 1/2".
For each side, you need 2 strips, 1 7/8" each: 19 3/4" + 1 7/8" + 1 7/8" = 23 1/2" minus 1" for seams = 22 1/2.
I hope this is clear enough. Sometimes, I just make things more complicated than they need to be.
