Re: Can you custom make a t-top canvas?
You can get grommet kits and tools from just about any place that supplies. Spur grommets hold best- The easiest tools to use for a smaller project like this use a hammer and die to set them.
You'll have to do some sewing, too- At a bare minimum you'll need to sew all around the edges, and you might need to sew more than one panel together if the fabric isn't wide enough. It's not hard to do- A T-Top is probably the easiest project out there!
