Made a ~50L pack liner out of 1.0 oz Dyneema to fit both my larger ULA Catalyst backpack and my Osprey Mutant 38 mountaineering backpack.

The design minimizes seams and uses folded darts to create a domed bottom and elevate the bottom seam by about 8 centimeters. Fully seam taped to keep water out.

The roll top uses 4mm foam as a stiffener and 3 snaps to hold the edges together before rolling. A 15mm (5/8") Magic buckle snaps together when closing thanks to small magnets in each half.

The Bio Hazard alerts anyone who dares to open the liner after sweating for several days in the great outdoors.

Total weight: 58gr.

This is absolutely what I want.

Sewed a new cover for the mini greenhouse. The old one had completely disintegrated in the sun. Re-used donated zippers from an old hot tub cover.

The 6 mil plastic sewed fine but the large canvas and the slick material were at times challenging to control.

Pleased with the outcome and happy to #repair, #reuse to extend this greenhouse's life. I call it re- #MYOG : Re-Make Your Own Greenhouse. ツ
