I've quilted quite a few charity quilts on my Innova, and in most cases I was given batting and backing that were properly sized for longarming the quilt, but never thread or any form of payment. (That's okay, because I prefer to choose my own thread, and I didn't expect payment.) In a few cases the batting was not supplied, or was very poor quality, or was not cut to the right size for the quilt, and occasionally I was given fabric for the back, but I was expected to cut and sew it to the right shape. These were efforts and expenses that I didn't expect, and I quit offering my work to these groups. If you're offering to longarm charity quilts for a group, it would help for you to have an understanding of what you will receive from them. I know that the guild I recently joined provides good quality batting and backing already prepared for loading on the longarm. The longarmer donates thread, incidentals like needles, time and experience.
