I'm piecing together some blocks right now that are definitely a challenge for me. I know for your seams to match up correctly it all depends on you cutting accurately, sewing 1/4" accurately and pressing accurately. I certainly do my best to do all that as well as I can, but I still have seams that don't line up. How can you ever do everything perfectly, so your block comes out perfectly?! Is it just a matter of years and years of practice?
I'm not the type that can seam rip over and over until it's right. I just don't have that kind of patience. My straight seams are all matching up, it's these angled pieces that you can't match up while pinning that I'm having trouble with. I can't see that they've matched up, or not, until I sew and press open. I can kind of pin it in place and open it a little to see if it's close, but can't tell if it's exact until it's a done deal.
I know there's probably no magic tip that can help me. It's the same 'ole cut well, sew a correct 1/4" and redo it if it's not right. I just needed to complain. :P
