Here's one idea:
Happy Holidays! ...maybe this will be of help:
How big? As a tabletop decor piece or a full size model for your yard?

A couple of my neighbors have built them too. They made it to screw together so when the holiday is over they can dismantle and store flat.
If you need more, let me know! 🎄☃️🍭
