For a DIY mermaid costume for your baby, make a wig by crocheting a beanie onto a yarn piece.

For the tail, use about a 1/2 yard of netted blue sequin fabric with some stretch in it. Check out full tutorial here.
Mouse in a Mousetrap
It’s a great idea to incorporate a transporting device for your baby’s Halloween costume since they’ll be wheeled around the whole time they’re trick-or-treating. This Mousetrap was made out of Birch wood, sponge for the cheese, and painted PVC pipe with irrigation tubing for the coil. All of this was rested on a wagon with a mouse costume to top it off.
