request to be in the build a jib cult, and everything that you need is there.
but basically you're gonna need indoor/outdoor carpet, a drop ( if you dont have a hill), wood, screws,pvc, and screw from the bottom up. basic
go with pvc for summer and metal for winter. pvc slides good in the summer but when it gets cold it breaks super easily. and metal is sticky in the summer but good in the winter
