Oh my goodness! What CAN'T you do with pool noodles? They're starting to rank up there with pallets;-) Check out this clever little idea! Use pool noodles as life sized lincoln logs. Just cut notches in each end. Cut to various sizes for smaller or larger logs. Here's a written tutorial via the DIYNetwork. Now, I don't know where you'd find brown pool noodles BUT even better, I found this little tutorial via Miss Kopy Kat about covering pool noodles with wood grain contact paper which would look more realistic. I've seen wood grain contact paper for sale at Walmart for pretty cheap (like 18 cents a square foot cheap). You could also try paint but I'm not sure how messy that would be.
