I have made many rag quilts. My family loves them. The only scissors I will use are Heritage Rag Snips. I have tried them all, every brand. I will never use regular scissors to snip a rag quilt after that first one I made that way.

If you only make one rag quilt the scissors are worth it.
I now use the Go rag dies, small and large. No snipping ever again for me.
