Quilting Weights

Quilting weights, but could be used for whatever you want to hold down.

Based on https://www.thingiverse.com/thing:2919135 per a family member's request. SuperIngo's is definitely prettier.

Mostly because I knew I had a whole bunch of the washers like the description below. These thread together so you can add additional weight if need be or simply for storage. They'll fit two washers each, but they're snug. I pounded them into place with a small hammer and punch, but they're not going anywhere.

Steel Flat Washer, Zinc Plated Finish, ASME B18.22.1, 1" Screw Size, 1-1/16" ID, 2-1/2" OD, 0.165" Thick
