Next time you need to stretch canvas or some other fabric, like when you’re repairing that favorite arm chair, rather than trying to pull the fabric taut with your hands alone, grab a pair of canvas stretching pliers like the pair from Alvin & Company pictured above
Alvin & Company manufactures these pliers from steel and then chrome plates them. The wide jaws have matching teeth that grip the fabric firmly without damaging it. The handles are spring loaded, but you can flip the spring mechanism out of the way if you don’t need it.
You can pick up a pair of canvas pliers for anywhere between $17 to $25.
