Using leftover materials fr other projects, u can create some lap pillow that doubles as a table of sorts...
Step 1: Materials:
No need to mention tools here; it's a fairly intuitive Instructable!
Cut the thin board of ply wood to the shape you desire for your desk. Make two of these.
Cut the foam pad to match the shape of the desk.
Cut the the padding slightly bigger than the foam (enough to engulf/cover the full thickness of the foam).
Cut the fabric even bigger than the batting.
Step 2: Assemble!
Cover the foam with batting.
Cover the batting with the fabric (don't forget to center the pattern on the fabric if it's geometric or has a high repetition in the pattern).
Pull the fabric edges over and under the wooden board, staple the edges into place, and trim the excess material.
Step 3: Velcro
Step 4: Prep the Table Top
Step 5: Uses...
Then, if you need a functional tray, flip it around with the desk-top side!
Pat yourself on the back for a job well done...
Namaste and happy 2016!
