How much does it cost to sew on a patch?
Sewing on Patches
In general, a seamstress should charge at least $3 for each patch, but even that is not enough. This sort of sewing requires one to be quite precise, so extra effort is a must. Up to $10 is a good price if we are using a sewing machine.
How do you sew holes together?
Lay the patching fabric under the hole, right side up. Then, bring the edges of the hole as close together as possible, without puckering the hole. Use a small zig zag stitch on the sewing machine to stitch around the edges of hole, catching as much fabric (patch and garment) as possible to make the patch hold.
How do you tell the difference between iron on and sew on patches?
An iron-on patch has a layer of adhesive on the back, which is activated by the heat of an iron. If the back of the patch appears to be only fabric or embroidery threads with no signs of an adhesive coating or backing, it is most likely a sew-on patch.
