I bought this ruler from the vendor and REALLY like it. I'd only used it on my longarm, but her new video shows using it on your domestic sewing machine (DSM). I immediately got my ruler from my shop, made a small sandwich and tested it on my DSM-- it REALLY works nice!!!!!
If you'll look back in my listings you'll see I did some curved crosshatching on a customer's quilt. I used AccentsInDesigns curved ruler to do it. :thumbup:
I am in no way affiliated with this company..... :mrgreen:
