The Go! cutter has been a blessing to use since I now have shoulder issues. The strip dies are great for cutting strips and then submitting them into squares, triangles, etc. I started out with the manual cutter when it first came out.
Recently I found another great use. I was working on a star block with four pieced squares and five whole squares. Well, each pieced square had two seams where the first seam had to be trimmed first before doing the second seam. I used the 6.5 strip die to trim away the first seam and again for the second seam. Then, because the block was 5.5 inches UF, I used the 5.5 strip to square off the blocks. Lot of time was saved, and there was less pain for my shoulders, yay.
