Thank you, Tartan. I usually pin. I've tried basting spray a couple of times in the past, and while it holds everything together really well, it also got all over my machine and all over my gloves. I'd really rather not use that again. Normally I do start in the middle and work my way out, but I'm doing a horizontal wave pattern this time, and I'm not exactly sure what my best line of attack should be.
Going to see if I can post a picture of the pattern I want to use. I did a quick sketch to give myself an idea of how it would look. Having trouble uploading it from my phone, so I'll try moving it over to my computer. Give me a minute!
