Loosely Woven Fabrics without a backing
How do you work with a loosely woven fabric that has no backing, that easily unravels?
When we ask this question it mainly applies to sewn edges. If you are just covering wraparound dining seats that have no seams, then there isn't much of a problem. All the edges will be stapled in place, so the edges can't unravel.
Now, what do we do with a fabric where we have to keep it in place when we cut it, sew it, and after it is on the furniture? There at least several things that can be done.
Serging: Some fabrics can be helped by serging around the edges. Cut the fabric at least 1/2 inch larger all the way around the to-be-sewn edges. Then run those edges through the serger at the correct edge.
Spray Backing: There is a product (perhaps there are more) called Sprayway No Fray Spray. (Test on a sample first). Turn your fabric over and spray along all the to-be-sewn edges and allow to dry. Depending on the situation, sometimes it may be advisable to apply several applications, letting it dry between each time. With each application the spray stiffens the fabric and makes it easier to sew and less likely to unravel. (Be sure to use with plenty of good ventilation. Read the health hazards on the label)
Have a Backing Applied to the Fabric. Here is what Custom Laminations has to say about their process:
