-A dark green sweater - I got mine at Burlington. It had this weird detachable cowl neck so I made some alterations and attached it so my neck would be covered. The sweater I found had a hairy texture too which was perfect. Honestly, I don't know what you would use it for besides an ugly sweater.
-Faux pine garland from Michaels. I used 2 and cut each on 4 pieces.
-NEEDLE AND THREAD (preferably extra thick thread)
-Lights with a battery pack - I used 2. The batteries were the most expensive part so be ready. These battery packs needed 2 C batteries and the 4 batteries cost me almost $20. Whatever, I wanted lights.
-Decorations. I went to a dollar store and got pine cones, silver garland and assorted Christmas balls. I also got cute candy canes at Michaels
-Ribbon for the tree topper
-Fishing wire in case you need to hang anything that doesn't already have a loop.
-If you want to also do the Christmas Tree thing to your hair like I did you will also need hair spray (I needed 2 cans), those clear small elastics for your hair, a hot glue gun, thick wire and thin wire. I just used the wire form last year's Snow Globe sweater.
I had a little bit extra left at the bottom so I cut it off with pliers and used this pieces to cover up some bald spots I had in the middle.
It did take me 45 minuted to undo my hair and wash out the green and it was still knotted mess and I had to cut a few knots out. But I had fun so it was worth it!
