I'm trying a paper piecing project for the first time. I won a "Tin Box Sampler Series" of gorgeous crackle charm fabrics as a door prize. There are very minimal directions with it to make nine Courthouse Steps blocks. I figured out the cutting, and construction, but now I have a couple questions. On the paper foundation pieces there are TRIM lines and SEAM lines. It seems that I would trim the blocks with the paper still attached so I can follow the lines. Do I also stitch the blocks together with the paper still on? Do I trim and then remove the paper? Also, since this project ends up being 12" X 12" what size binding do I use....narrower than for a standard sized quilt? Thanks for any help.
