question from the mathmatically challanged

OK. I want to make a type basket weave quilt and I can't figure out how wide to cut the strips. I don't have a pattern, just trying to make something I saw hanging in a quilt shop this summer. I can't go look at it again because it's a 2 day drive away! I'm using 3 colours (D,M,L) in 5 rows...

DDDDD LMDML DDDDD MMMMM LMDML MMMMM LLLLL LMDML LLLLL MMMMM LMDML MMMMM DDDDD LMDML DDDDD

make sense? If I cut the strips at 1 1/2" I would end with 5" finished, right? If I cut the strips at 1 3/4" I would end up with 6 1/4" finished???

I'm going to sew the strips together and then cut them at ??? to make a square.

If I cut them at 11/2", sew them together, would I then cut the strips at 5

1/2" to give me 5" finished?

I'm not sure I can help you with the math part, but if you cut your strips WOF ( width of fabric ) and sew them together, then you can use a ruler with a 45 degree line on it. Just line it up on one corner, and cut when it hits the opposite corner. That will give you a square.

Five 1 - 1/2" strips sewn together and cut into squares should give you a 5" finished block, ie a 5 -1/2" square. Sounds good to me!

YES. You cut them at finished size plus 1/2 inch.

My own problem is not the math--I can do math problems. Where I get into trouble is alternating back and forth between "finished" and "unfinished" sizes.

When you start out with a block, you're generally in one of two positions:

  1. If I *start out* with pieces X size, what will I get as a finished block?
  2. If I want a *finished* block at Y size, how big do I need to cut my pieces.

I find it's much easier to work backward from Position 2, adding 1/2 inch all around to every piece. Otherwise, I often find myself with too-small pieces, that I've inadvertently cut to the finished measurement.

HTH.

Thanks, Patti. That was part of the question. I can see now why cutting the set the same width as the group of strips makes sense, I'm lost when it comes to figuring out how wide to cut the original strips. You're right - I started this thinking it was going to be tricky! I wanted a set of strips

6" wide and started working from there trying to keep in mind seam allowance and so on. Then it dawned on me that each strip will lose 1/2" in sewing. So I came at it from the other side. Cutting five strips 2" wide is actually 5 X 11/2= a 7 1/2" finished block. Yah? Then I cut the set at 8" so when I sew it up losing 1/2" I end up with 7 1/2". (Please say I've got it as this has now become my reality, lightly grasped tho' it is )
