We all have been their. Nice day we go pinicing put the table cloth on the table to keep everything clean from other things to us. We get the food out, get our plates full then the wind pick's up or someone move's the table cloth & their goes our plate's we say darn wind or someone's name. Well here's a way to keep that from happening CHEAP.
Start out with a 2" peice of PVC. I made all mine 1" wide. They work just right. But each to their own. Good Luck.
Cut to 1".
Burr's. Make sure you have leather glove's when deburring. TRUST ME. It hurt's if you don't.
Make sure you make a smooth edge on the inside of the clamp. That way it won't tear your cloth or anything thin.
Any size you want. The thinner the table the thinner the clamp.
Two different size's.
If you cut at an angle cut the thin part out to make the opening. That way you have the wider part on the outside. Less stress to break. You just have to be creative.
