A reader asked if I'd post a detail shot showing how I pin a curved block. No problem! Here ya go :)
As you can see, I pack those pins in there pretty tightly but, as I said in yesterday's post, if you want super smooth curves you just can't beat pinning. I first divide my curve into quarters (or eighths, depending on the size of the block) and mark the quarters with pins. I then match my centers and pin them together, then match the beginning and end of the stitching line and pin, then match the quarters and pin. Next, I carefully match the sections in between the pins together, making sure the edges of my fabric are aligned, and pin. Yes, I know, it's a lot of pins but the results are worth it.
When stitching, I do not remove the pins as I go but instead I leave them in place as I feel that it gives the fabric more stability and prevents any shifting of the layers. I stitch slowly and try not to crash and I make sure that the pins I use have round heads so they'll roll out of the way when the needle gets close. I do not *ever* use flat head pins when doing this, as they won't roll and will make it more likely that I'll whack a pin with my needle.
Let me know if you have more questions!
