Sewing machine needles-you mean you're supposed to actually change them and not wait until they break? Once I realized that machine needles should be changed, sewing triangles became so much easier.
I was addicted to crumb quilting for awhile. It felt so good to basically make fabric out little tiny scraps of fabric-anything bigger then 3/4" , but after ~ 1000 blocks I couldn't stand another crumb. I bagged everything less then 4" up and gave to a friend who makes pet beds for the local animal shelter.
