Step 7: Assemble the Shelf!
First, the six to eight original pieces of cardboard we cut out in Step 3 will be lined up on edge. Next, the pegs can be inserted into the pieces. Try to evenly space the sections made in Step 3 across the pegs. After this, the shelf should be coming together quite well. Next, glue the main rectangles in Step 5 in their appropriate places along the edges of the sections made in Step 3. If you need to visualize this, check out the photo on Step 5. It will show you where each rectangular piece will go. Remember that the pieces B and C will need to be creased where they enter the V .
Once you have completed this step, you are basically done! In Step 8 we'll cover up some seams (optional) and in Step 9 we'll hang it.
