Trackmate :: Simple Shoebox Sidekick

Step 3 Add in the support blocks

Next, we'll need to add in the support blocks to hold up the picture frame.

1. Measure the thickness of the picture frame with a ruler.

2. Make marks inside the box (the same distance as the thickness of the picture frame).

3. add some hot glue, and glue a block into each corner. The picture frame should now sit nicely on top of the blocks. If it seems like the picture frame can fall through, try using larger blocks.
