I love these coasters and they were very easy to make!
I made 6 of them using Moda Flannels http://www.modafabrics.com/
Cut 12 squares of fabric 6 1/2 by 6 1/2.
Next cut your quilt batting I used Warm & Natural it's my favorite. 4 1/2 by 4 1/2.
I used 2 squares of batting on each one and they are real plump.
Place the quilt batting in between the fabric squares on each .
Now just make a big X , sewing from one corner to the other.
Sew a 1" border around each square, that keeps the raggedy part from crossing the stitching line.
Last cut slits around the entire outside of each coaster. Be careful not to cut into stitching line.
The smaller the cuts the more raggedy it will be.
Toss into the washer and then dryer and you will have raggedy coasters.
