Well, that's a great question! If you're looking to make an outdoor Christmas tree frame, you'll need a few supplies. First, you'll need a sturdy base to anchor the tree, like a piece of plywood or a sturdy cardboard box. Then, you'll need some long, straight branches or pieces of lumber to create the frame. Once you have those, you can use zip ties or rope to secure the branches or lumber together, creating the shape of a tree. Finally, you'll want to decorate the frame with lights, ornaments, and other festive touches.
