The above age and time guidelines are estimates. This project can be modified to suit other ages and may take more or less time depending on your circumstances.
Cut a piece of fur 3-inches wide by as long as you want your inch worm to be. I made mine about 4- to 5-inches long. Cut a piece of chenille stem about a half an inch shorter than your fur piece.
Spread a generous amount of glue all over the back side of your piece of fur. Lay your piece of chenille stem onto the glue, about 3/4-inch away from one of the long ends. Fold the piece of fur in half lengthwise, glue sides together, lining up the edges as good as you can. The chenille stem should now be enclosed in your piece of fur.
Now glue the two wiggle eyes onto the fur as shown in the picture. Glue a pom-pom nose in place near the eyes. Let the glue dry completely.
Once the glue is dry, you should be able to bend and shape your inch worm however you want!
I got the fur fabric I used here for free using one of the sources I list in my article: Free Stuff for Crafting and Kids.
