I've gotten so many requests for this that even though I never use a cart cover myself (Stephen's old enough not to gum the cart handle, and Sophia rides in my sling), I felt it was time to sit down and tackle the problem. I'm trying to do this without copying anyone else's design, but I'm sure I will inadvertently incorporate features of existing cart covers, simply because there are only so many variations on a cover that will fit a cart. Any such resemblance is purely coincidental, however. I do own one cart cover, but I'm not wild about its design, which does not seem to be original in any case.
these suggestions include no-sew directions (using polar fleece), some sewing (using fleece and fold-over-elastic), or lots of sewing (using woven fabrics and bias tape).

the very simplest cart cover, at least in terms of its shape, is a shape with a drawstring or elastic in a casing around the edge. A standard cart will require a rounded rectangle (in this case, a square with rounded corners) that's about 45 " long and 45" wide. You can use two layers of fabric, or use one sturdy layer and some wide bias tape. You can also make it with 90-degree corners, but I think it's much harder to thread elastic through the corners.
If using two layers, first cut out the leg openings and hem them with a single-fold hem -- you could even baste the hems. I think it's best to measure the cart before cutting the openings, since they're all slightly different, but putting the top of the leg openings about 12-15" from the edge (so that the bottom of the opening is about 16-20" from the edge) is fairly safe.
Sew the two layers together, right-sides together, so that the leg openings match up, leaving about 1/2" unstitched at the front edge (in front of the space between leg openings). Turn right-side out through one of the leg openings, then sew the leg openings together -- if you basted them originally, you can use the basting stitches as a guide, then remove them when you've sewn them closed. Stitch around the outside about 3/4 " from the edge, making a casing. Thread a drawstring or some elastic through the hole in the casing.
Voila -- a very quick cart cover, which will also work as a high chair cover. I made one like this and it works fine -- a lot puffier than I would ordinarily prefer, but it does the job and Sophia likes the Hello Kitty print!
Here are the dimensions of the carts they have at our Shaw's Supermarket:
Warehouse stores, WalMarts, and other stores all have different carts, though, so I'd recommend measuring the carts you use most frequently, in case the dimensions differ significantly. (Here is a printable GIF you can use to write down the measurements you've made. Remember to make a note of where on the seat back the safety straps are attached.) the side, back, and handle extensions are all somewhat longer than the sides, back, and handle portions of the cart, to allow for some overlap to keep those surfaces covered; the handle and back portions are also wider than the actual cart, sothere's some "ease" in putting it on the cart.
A more involved but more fitted cart cover will necessitate more cutting. You can use the dimensions above, or your own measurements. You can cut all the angles as shown in solid lines (outside only, obviously!), or use the dashed lines to make a continuous seat portion. Without the fabric within the dashed lines, the inside of the cart seat will be open on the edges. You could sew those edges together, making a fitted seat, but then it will really fit only one type of cart. If you can, I'd recommend using a very large piece of paper to make an actual pattern. You can have it just 28" wide, as the cover is bilaterally symmetrical, but the paper will need to be at least 28" by 42". An unfolded paper grocery bag may suffice, if you tape another sheet of paper to one side for the side extension. otherwise, you can try to mark your measurements and layout directly on the fabric, making sure that all your right angles are really 90 degrees each time.
For fleece, all you really need to do is cut -- no sewing is strictly necessary. Then apply some hook-and-loop tape to the sides of the handle and back extensions so they can be fastened around the cart, or use diaper pins to fasten the extensions into place, or apply snaps. The h&l tape and snaps will be best applied after you have tried the cover on your favorite stores' carts, so you know where best to apply them. I'd recommend using diaper pins on your first trip, then analyzing where to put permanent fasteners afterwards. Or just stick with diaper pins :)
For woven fabrics, if you're using a single layer, just cut around the outsides as you have determined them, then finish the edges with a serger or bias tape. Cut the leg holes and finish them with bias tape. For a double layer, sew the two fabrics right-sides together, then turn. The outside edges will all be finished, and you'll need bias tape only for the leg holes. Attach fasteners as above.
For either fabric, make long buttonholes for the cart's safety straps. About 1.5" should suffice -- they should be long enough to allow the buckles to be brought through.
I haven't made one of these for myself -- these are all just suggestions, and as such, I'd appreciate some feedback if you choose to make one. I believe the directions are sound, especially for the polar fleece, but please let me know if you run into any trouble.
You may want to add a toy loop or two to the front of the seat portion, or leng then the side extensions to make pockets for yours or baby's stuff. You can use bias tape or self fabric for the toy loops, and just fold the fabric upwards to make side pockets -- they will hang on the outside of the cart, and depending on their depth, can be used for a water bottle, coupons, other toys, or whatever else you like to have at hand.
I'd recommend making a simple drawstring bag to hold the cover when you're not using it. Scraps from the cover itself should be more than enough to make one. Fold the cover up and see how big it is, then sew a rectangle from the scraps that's big enough, leaving 2" free on one end (that'll be the top). Make a casing in the 2" you've left, so that the sides are open -- that's where the drawstring will go. Cut two pieces of ribbon or bias tape or string (whatever's handy) to 2.5 times the width of the bag, then thread them through the holes. Each drawstring will go through both of the flaps, making a loop on one side and a tied end on the other, so that the tied ends are opposite each other. Or you can use just one drawstring, but I find the two-string bag to stay closed better, and open easier.
Sherron T. says: For the buckles it would be nice to use your own instead of the dirty ones on the cart. I guess that you would need to have two sets of buckles, one to attach the cover to the cart and the other to put around the baby. Or one loose belt would work too maybe? the second idea I have is to put a pocket on the cover that can be used to fold the cover into itself to store.
BJ A. suggests these alterations: I used navy blue ribbing around the leg holes for added comfort on my grandson's legs. I put 2 large buttonholes opposite the leg holes and bought a webbing strap with buckle so it can be threaded out the back to be attached to the cart, so baby has his own seatbelt too.
Treece A. adds: I really like your pattern ideas and need to make one for my 8 month old. I have one that I purchased for my last baby, but it doesn’t cover the sides of the cart. One thing that it has that I like is the belt. It has the two long buttonholes and one long adjustable strap. You take one side out and thread it through the back of the cart’s seat and back in through the buttonhole and around your baby. I am going to use mine as a pattern or just use it all together when I make a new one.
