These fibers may be heat bonded together to produce a nonwoven type of fabric. Heat bonding occurs when the "hot fix" Angelina fibers soften and fuse together. Place a small amount of fiber between two sheets of tissue paper. Heat iron to silk setting. With little pressure, move the iron back and forth, checking frequently on the bonding progress. Angelina fibers are lots of fun to use in your artistic creations and may be used directly on fabric or combined with other threads and/or yarns. Stitch it, paint it, twist it with other fibers. OR...How about using it in your paper crafts?! Think handmade greeting cards, paper or fabric boxes, picture frames, books/book covers, etc. NOTE: Generally Angelina® "hot fix" fibers only adhere to themselves and not to other fibers such a paper or fabrics. If you wish to adhere to other fibers you will need to use a separate bonding, fusing or adhesive agent or adhesive. These fibers are polyester and hand washable. Lay flat to dry, do not put in a hot dryer or re-expose finished project to direct/high heat.
