There is a place on Route 108 heading down towards Scarborough beach. Its next to a muffle place. Just after the CVS in Narragansett/ Wakefield. It's a small little place, on the left side of the road if your heading to Gal. Its next door to a muffler place with a little man made out of mufflers infront of it. Pretty good directions huh? I know silver spring marina up at the salt ponds in narragansett does canvas too. They are off of route 1, take the Marine Park exit and they are under the bridge on the left next to the coffee shop, right on the upper salt pond.
Good Luck!
