I need a small amount of sail material (Dacron?) to repair a Laser sail. I'm not sure what weight material is used for the Laser? I need a piece about 12" x 12" to repair the mast sleeve near the top of the sail. I also need some thread, while I'm fishing. If anyone has some to sell let me know. Or, if you know of a retailer that would sell a small amount let me know that also. Thanks!
