After retiring from teaching art for 32 years i have had the chance to get back into the studio. Last year I did three shows. Two were inside and the one outdoor show provided a tent for "emerging artists". So this June will be the first outdoor show on my own. I purchased an eze up 10x10 tent last fall when eCanopy had some great sales. Used it Winterfair Columbus, an indoor show, worked great. But I have not yet purchased/made weights that I will need for the June show. This show is on parking lot surface so the tent can not be staked, just weights. I need some advice on weights to secure the tent. How many pounds? How to best tie to the tent? do I purchase the weights? Do I make something of my own? Would appreciate any advice.
