The mats sound like a good idea.I used to made cloth books with zips velcro fastening,buttons( must be secured between double fabric),fur fabric,lace etc.I also put in suspender fasteners and bra clips, great for the fellas too.The mats would be much quicker to make though,and as my stash of all the bits and pieces are now sadly declined I could find enough for them.Well done Love Letty
