My babys costume idea...lmao need help

any creative mommies out there that can probably help me out? I'm dressing up my baby as little red riding hood for her first birthday party but i wanted to make a house out of her walker! I was going to decorate it with fake grass/flowers then fur for the bad wolf and the roof with hay or straw like material and add a basket. the only problem is idk what to use for to build the house. I was thinking maybe i can use cardboard would that feel too flimsy?? maybe wood? I'm excited for this project and hopefully it comes out right. don't mind my editing draft I was in a hurry! lol any suggestions? I'm also going to add opening Windows on the side
