Here are some of my ideas:
If they are the boxier kind, building blocks for kids
Barbie Clothes Trunk
Snow or Sand Fort Brick Molds
Car First Aid Kit, fill one for each vehicle with bandaids, alcohol wipes, etc.
Car Kleenex Holder - Kleenex boxes always get smooshed in my car, so take the kleenex out of the paper box and put them in baby wipe box for durability in the car
Craft Item Organizers
Ribbon Holder - Get a small dowel rod slightly longer than the baby wipe box, cut two holes in the opposite sides of box for the dowel rod to fit through, thread spools of ribbon onto the dowel rod and then insert it in the holes and now you have a box of ribbons where you can just pull the ribbon off the spool without getting tangled messes
Planters, using 2, Cut one in half (cut off top half) and the other one cut some holes in the bottom. Nestle the holey one in the cut one and fill it with a plant or herb garden for kitchen window.
There were a few things I already wrote on the blog in the past about how to use them.
Do you have any ideas on how to use a lot of baby wipe containers besides the above? Leave them in the comment area.
