We recycle plastic bags, and the plastic bag full of plastic bags hanging on a door handle have been getting on my nerves. So I did a little digging online, checked a couple of tutorials for ideas, and made a plastic-bag holding tube!
I started off with a fat quarter, and backed it with fusible fleece. I picked fleece because I wanted a little extra sturdiness to the bag, and the roughness of the fleece on the inside of the tube should help keep the bags in place better than a smoother interfacing.
I cut off three inches from the long side of the fat quarter, to make a narrower tube. I sewed that 3″ strip into a tube (wrong-sides out) and turned it right-side-out to use as a loop for hanging the bag. Next time I do this, I’m cutting the 3″ strip off first, and then fusing on the fleece. Turning a 1 1/2″ tube that’s backed with fusible fleece inside-out was really exasperating.
Then I dug into my scrap box, cut two pieces of black fabric 2″ x 15″ and made them into 3/4″ draw-string tubes at the top and bottom of the soon-to-be tube.
Two pieces of elastic later, (8″ on the bottom, for a small opening, 12″ on the top, to make putting bags in easier) I sewed the whole thing up the side, and flipped it right-side out, and ta-da!
Now it lives in the coat closet, where it hangs very nicely on one side and is up high enough that we can all reach it easily, and the best part? It doesn’t clutter up the hallway anymore.

I keep meaning to make one of these! Mine are all balled up and semi-contained on a shelf in my linen closet. This would be much, much better! You’ve inspired me to do this sooner rather than later.
that looks so simple–I should really make one to get rid of the ‘box’ of bags under my kitchen sink!
