I bought a decorative box at Michaels-- the ones that are covered with pretty paper and have a magnetic flap closure. It was pretty, but it wasn't Christmassy. I also bought 12 x 12 scrapbook paper to cover the box.
Before I started decorating the box, I needed to make some partitions. I decided to make 2 layers and cut enough posterboard strips to make them. Notice how I notched the strips. They slipped together easily. I put a piece of posterboard between the layers.
Now I was ready to decorate. I painted the top with a collage glue. I chose matt finish this time.
I added layers and borders because my box was larger than the papers. I used a contrasting paper for the sides. After the first coat was dry, I added a second coat.
I found a pretty B and printed the outline of mirror image on the back of printed paper. I actually did two, because I was going to make a shadow. I didn't like how it looked, so I just used 1 letter.
I carefully decoupaged it on the lid. (I put the other one on the inside.)
Done! Now I just have to mail it!
