I snap up sale fabric usually at Joanns. It is usually 100% cotton and age appropiate for my Linus quilts. I also like to use cotton flannel on the backs. I usually make my Linus quilts out of one pieces of a children's print on the front and a plain flannel back. I make them pillowcase style by sewing the three layers together and then turning them. I use decorative stitches and usually some kind of varigated thread to quilt them simply about 4 inches apart crossways and then about 1/2 around the outside edges to make a self binding. This method allows me to produce about 20 a month. Our county chapter of Linus averages about 600 donations of quilts a month.
