Nice job and i know they are appreciated!
i make "cage comforters"
http://www.pleasebekind.com/ccp.html
for the local animal shelter..i use the batting that is 1" think and on a roll. it runs around $25 without a coupon. it is 24" wide. usually someone donates it to me, and i do the sewing, i can't afford to buy it myself.
I made about 70 scrappy quilt tops, most measuring around 14 x 20, i supplied the backing..and one of the ladies here,
( sunkistmi - Wendy )came to my house to pick them all up.she sewed them all together..and she donated them to the rescue. she does fostering for kitties..and helps place them.
