I pinned this a while ago and absolutely LOVED the idea of it. Not just for produce either(which was what the Pin labeled these as), I think it's such a cute bag, period. So I made some. Guess what? I looooove them. I want to make more. I actually considered going and buying some t-shirts in colors I liked just for these bags. I didn't do that though, I realized that would be a little crazy.
Take an old t shirt, flip it inside out and cut out this shape(kind of like a 'U'), as big or little as you'd like. Go from the bottom up, that way if you want to keep the hem that's around the waist of the shirt you can. Some I kept on, some I cut off. Next, stitch around the three sides to make your bag shape. Next step is your holes. I traced mine with pen first. Make sure you do your handle first, then a few inches down start your holes. I staggered the slits too by the way!
Now it's time to snip, snip, snip. Snip all your slits!
When you're done snipping stretch your bag out so the holes form. I washed mine after I was done so they would curl just a bit and also to get all of the fabric crumbs off.
Here I am modeling a bag of bananas, HA!
Another larger one, this one is more of a tote size.
All of the colors and sizes I made. I love the ones that happen to have some t-shirt logo still on them, gives it some extra coolness.
