Soap Baggie

So I have a lot of Peaches and Creme yarn leftover from the first sweater. It suddenly occurred to me that it might be possible to make a quick little bag to go over a bar of soap, along the lines of the ones I've (rather endlessly) crocheted.

For the record, here's what I did tonight. It definitely needs refinement.

Using KP 2, open cast on 15 stitches, leaving a ten inch tail Knit 20 rows. Completely unravel every other stitch, starting from the second stitch in. Run a piece of waste yarn through the loops that the ravel cord holding the weight on goes through, and a piece of waste yarn through all the loops on the needles. Remove the work from the needles. Don't cut the yarn.

Hang half of the length of the piece on ten needles, and hang the other half on top of the first (this is how the bottom is made). Knit one row. Remove the work from the needles. Don't cut the yarn.

Hang the original stitches through which you threaded waste yarn onto 7 needles, with an empty needle between each inwork needle. Hang the loops that original held the ravel cord on top of these and knit one row. Cut the yarn, leaving a ten inch tail. Use a yarn needle to thread the yarn through the stitches on the needles, and remove the work from the needles.

Tie the two tails together in a knot. Use a yarn needle to run them between the first row of stitches around the opening to create a tie. (Note: this part needs to change. Perhaps an i-cord would be suitable.)

Put a bar of soap in the bag, close the opening with the tie, and use in the bath or shower.
