fleece scraps
I make "Woobbies". I sew 5 to 6 inch squares into long strips using a 3/4" seam, then sew all strips together. I don't worry about getting like colors side by side. After I get them all together I snip the seam allowances. Fleece don't fray like denim but will curl, the more it's washed.
Every one I've given one to says "NOBODY GOIN' TO GET BETWEEN ME N MY WOOBBIE".
