I think for the 3 dudes block you can get away with the strips not being the same size, you'll trimming the sqares anyway - if that's the one I'm thinking about-sew the strip sets together all around the block and then cut on the angle to get hst?

I made this with all my scrappy leftover stips , just randomly sewed strips together with no care about size, then trimmed up the squares. I think it adds some character when the strips are different sizes.

The 2nd one,I had sewn all the blocks and when I laid them out someone said, "why didn't you do a square within a square instead of all that extra work?" Then I saw what she was talking about and went back to the video and realized I skipped a step. It's a design element now. I think it's interesting.
If this isn't the one you are talking about-ignore this entire post please.
I don't buy precuts often, only when they are a great price on clearance. I can mess up the cutting all by myself, I don't want to pay for someone elses bad cutting.
