Next, the top! I have used wide bias tape to do this and since there are so many colors available it is a easy choice. I did not have any that matched my fabric, so I used a piece of green fabric cut on the straight of grain. The fabric I picked has a lot of give to it as you can see in the picture. Try to choose one that has a lot of give, or you can cut your own bias strip to coordinate with your other fabrics.
Run the glue stick down the center of the strip a few times to give it some hold. Gluestick one end to clean finish it like you did the fabric for the body. Starting with the unfinished edge, wrap it around the plastic part of the lid and stretch it as you go. Cut away any excess length rather than covering it over, to keep the lid fitting well. At this point I put 3 or 4 stitches in the fabric at the rim to hold it securely together.
