Today, I cut 540 (4" finished) HST's on my Go machine to make a navy blue and white herringbone quilt. I've already sewed 1/3 of them, in addition to sewing on the binding to 6 placemats, and finishing 6 blocks for another quilt. And, I read 1/3 of the book I started the other day. Not a bad day.
I could have never gotten this much accomplished without my Go. The HST's went together very nicely, in fact, I carefully sewed 1/4" seam, and it appears they came out so perfectly that I don't even have to square them.
You will love the accuracy of the cutting with a Go machine.
