Well, I came across this great walk through on how to make a shopping cart cover, so I wanted to make one, or two, and share my experience.
Here's a pic of the finished item:Prepping the fabric:
Measure out two parts, 45X42 inches. Fold each in half from bottom to top, then again folding to the left. Round out the tops along the left top side.Theeeen, measure from the left side 19 inches in, and about a hand's width up form the bottom and make a circle for the leg openings. You could make them square as well, or just about any other shape you want too.
After that, measure from the RIGHT side, about 7 1/2 inches in and a hands width up and form a 3 inch line, cut through, for the buckle straps.Next, unfold both parts, lining them up together, printed fabric facing in. Pin all around the outside edge and sew with zigzag double stitch.
Make sure you leave a generous space for folding the whole thing right side in after you're done too!!
So after that, go back and make an elastic casing seam, about 3/4 wide from the outer seam. I used my thumb as a guide.
After you're finished with that, get your elastic ready, and grab a big sturdy safety pin! I had a flimsy crap one, so it was a bit difficult getting all the way around well. But attach the elastic end, then feed through. This takes a bit of time, and patience.
Then, once you reach the opening again, cut extra elastic off, leaving about four inches on both ends, sewing them together, twice for reinforcement.
The, pull it all through the opening you left (right??) and then, folding the fabric parts inwards, sew along there, stretching the elastic tight. Stitch stitch....
Then, find those leg holes, pin along after lining them up and sew along the seams with the faithful zig zag stitch.
Do the same for the straps lines as well, which was a bit tricky for me lol.
Then BAM, you are done-zo.
