Yeap, that's what I'm doing Jljack! :)
For matching the seams, I pin them on the 1/4" allowance, then open it up to make sure they match, & adjust if needed before sewing it.
For sewing the individual pieces together, I offset the top piece by the 1/4" allowance, which is sometimes a scant one.
And still have to rip a few of them out, but much less than when I started this!
I think one of the main issues I was having was it was right before DH had his surgery, etc, and I couldn't 'focus' enough on it.
