I’d like to see some patterns of the mesh market bag deals… I’d like to make a spin off of one of those. 
There’s plenty on the net - look through knittingpatterncentral.com or dailyknitter.com
here are two free patterns:

There is also one in the new issue of knitty. I think that it’s called BYOB (bring your own bag)
Here’s a few more, but I’m sure you can tons more if you check the sites Sue listed.

Knitty’s BYOB
The trouble with [I]most[/I] market bags IMO is that the handles are just too thin and not supportive. Once you fill it up it’s going to be heavy and carrying it on your shoulder is going to be painful. Maybe if you design your own you can take that into consideration and make a sturdier, fatter handle. 
Yep on the straps, plus most of them are knit a long garter strip and attach it to the bag, which stretches out and gets uncomfortable. I start from the bottom up, do a couple rounds of garter, then the mesh pattern, another couple rounds of garter, BO a few sts on opposite sides of the bag and CO a few more sts than I bound off, then a few more rounds of garter. Usually I grab the bags by the top, but can use the handles if I need to.
I’ve made the everlasting bagstopper from Knitty.

You use ribbon for the handles so it doesn’t stretch like a knit or crochet handle will do.
Thanks everyone!!!
I really like the Everlasting bagstopper!! I’ll be making something simalar.
I ended up maknig something yesterday… Not perfect and no pattern cept the formula in mi brain… But it’s a mix of knitting and crochet. I wanted some of the traits from each. So I crocheted a round flat circle (big enough for a large ice cream tub to sit on and still have space in the circle.) and then I picked up sts all around with a 24" 10 1/2 knitting needle. I st st the first two rounds (I pm to show where the round started) and then after that, repeated these two rounds:
Round 1: Knit all stitches.
Round 2: Y/o, k2tog Repeat to end.
over and over until I got a nice bag size (1 1/2’) and then c/o with a crochet b/o and Sc around the whole thing. 3 rounds of sc, one row dc, 2 more rows of dc, and then I started the strap. I made that 5 sts wide, and crocheted those back and forth till it was long wnough. After that I attached it with a afgahn st variation. You know those little gaps on the sides of the sc rows? I crochet only in those gaps, and sc around one side of the strap and the same edge of the bag… 2 rounds sc. Then I repeated the same thing on the other side. It turned out really nice. I’ll have to see if I can use mom’s camera. The strap being crocheted back and forth, and then in the oppisite direction, gave it a really nice sturdy strap. I’m happy with it. :yay:
