Looks like Shirlener gave you the best answer, you can also use a tooping called Hide it. It will prevent the fiber from comming out trough the design latter on. Good luck, will be waiting to see your project.
pafhen, I usually will use a tear away on the bottom and two layers of the light weight (plastic looking) washaway stabilizer on the top. Good luck and hope to see you post your finished project soon. *4U
