To make them a little more sturdy, I glued them to cardstock. This is completely optional. We all know they're going to be destroyed at some point anyway. :)
The cutting took me all of 8 minutes during my toddler's nap time.
Cardstock to glue the "bugs" onto (optional)
If you have older children, you involve them in this activity as well by mixing in your own, homemade "bugs" that'll still challenge them, like sight words, rhyming words, etc.
