Used a pack and a half of this plastic-like twine
I bought 2 packs of these and used 2 of the middle-sized ones.
And here it is on the line full of pins--
Basically, I made it by starting out with a hat-like item, then I made it a little narrower for several rows before the opening. Hooked the carabiners between stitches and voila--a clothes pin bag! I did take notes on what I did so if anyone is interested, I can write it up.
Hope your week has started off on a good note.
