#shellchallenge #shell This is a shell challenge I made. Here are the rules, you may: add walls inside, add windows, add pillars, and add a deck. Basically you can do anything! The only rule is; NO CHANGING MY WALLS! Do not change any outside walls, you may add walls inside but you cannot change any outside walls. You can also change the roofing if you please. When done put it on the gallery with the hashtag #ButterflyKayShell You can make this into anything you want! #shells #house #houseshell
