how to attach straps to cardboard costume

Im wanting to make this costume for my son for Halloween and this is perfect! Finish gluing the rest of the oval over the cardboard base. First, use the XACTO knife to cut a square in the bottom of your diaper box. For less-standard forms like a star-shaped sheriffs badge or angel wings, first draw an outline of your desired shape on cardboard, then cut along the lines with a scissors. Cut 6 of the four-sided shapes which will cover the top and the bottom of the shell. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/45\/Make-a-Turtle-Costume-Step-1-Version-3.jpg\/v4-460px-Make-a-Turtle-Costume-Step-1-Version-3.jpg","bigUrl":"\/images\/thumb\/4\/45\/Make-a-Turtle-Costume-Step-1-Version-3.jpg\/aid699581-v4-728px-Make-a-Turtle-Costume-Step-1-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
