Step 1: Materials
1. 4 shims
2. some screening
3. a staple gun
4. hot glue gun
5. duct tape*
7. some fabric for grip and padding**
*please note: the duct tape and scissors are not pictured because I forgot to get them out until I needed them
** I cut up an old fleece scarf. fleece is good because it's thick and you don't have to sew the edges
Step 2: 1. Glue Shims Together
Step 3: 2. Staple the Screening to the Shims
Staple the screening to each set of shims once at the top of the thick end and then one more time a little lower. Be careful that your second staples are still high enough up and not coming through the other side.
The distance between the shims is up to you but be sure you have them level with each other. I used the floorboard to line them up.
Step 4: 4. Fold Over Thick End and Staple
You'll want to kink the screening between the shims to be sure it stays straight.
Step 5: 5. Fold Under and Trim Thick End
fold the center excess screening over (the fold will keep it from scratching your surface under your laptop as well as strengthen the support between the shims).
trim the excess ends off so they don't hang over the edges
I did also put some duct tape around the ends of the shims which you can see in the finished pic. I don't think it's necessary though
Step 6: 6. Fold Trim and Tape the Skinny End
Cut your duct tape to fit between the shims and tape the skinny end down folding the duct tape over the end.
Step 7: 7. Glue on the Fabric
Trim the excess and you're done!
