First I purchase a vintage shadow box. I have found these at yard sales, estate sales and thrift stores. I'm lucky because a friend bought me two that are shaped like a house at a thrift store.
Next I gather the ornaments and Christmas decorations I want to put in the shadow box. That will help me determine the size of the divisions. I use a Dremel tool with a saw blade to remove the dividers I do not need. I always remove dividers from my configuration boxes because the spaces are just too small.
These are some of the items I have collected year round for this project. I look for old Christmas light bulbs, vintage knee elves, old bells, old seals, putz houses, bottle brush trees, flocked Santas, plastic reindeer and more.
After removing the dividers I cover the inside of each square in scrapbook papers that will blend with the item I am going to place in that space. I use white glue using a brush to spread it smoothly over the area. I use an exacta knife to cut the paper. You could also use a paper cutter. I cover the back and inside of each cell.
I also put vintage garland and Washi tape on the inside edges of some of the cells to add more detail.
Next I put the ornaments and decorations in the cells. I use removable glue dots, white glue and even some hot glue to place the pieces in the cells.
Next I cover the edges of each cell with narrow Washi tape. I love Washi tape but it is not the stickiest tape I have ever used. I brush white glue on the edges before placing the tape on it.
Last year the local one dollar store had the cutest glitter cardboard Christmas ornament words. I bought as many as I could find before they got gone. I place one of these on top or in a cute place on the box. Here's my final piece. I really love it.
