I don't have room in my apartment for a board to be set up at all times (or a sewing machine, for that matter), so I devised a board that sits on top of the daybed in our office and folds up to be hung on the back of the door when not in use. Thought I'd detail the process here as it might be useful for anyone who hasn't built their board yet or is searching for materials.

The materials I used were:

1 old, flat door from my local building salvage shop (Rebuilding Exchange in Chicago) - $15

1 piece of salvaged common board for the legs - $5

Some hinges from that same salvage shop - $2

2 yds cotton moleskin - $12/yd

1 heavyweight industrial synthetic felt sheet - $50 (this took me forever to find - who knew felt was so expensive!)

Some spring latches, to keep the legs in place when folded up - $8

Door hanging thing (removed the part that you actually hang stuff from) - $10

These are probably only useful if you happen to have the exact same daybed as me, but here they are nonetheless

These split ring pipe clamp things, which perfectly fit the arms of the daybed. Also took a weirdly long time to find - $11

These nut inserts to I could screw the threaded rod/feet into the legs -$7

Threaded rod - $1

I made it so the legs + the threaded rod + the height of the daybed would put the board right at my navel, but you could theoretically make your folded legs up to half the length of the door.

Attached the legs to the underside of the board with the hinges, then screwed the legs in and got it all set up before putting the felt on top

The felt sheet was a bit shorter and wider than the dimensions of my board, so after I cut the width to the right size I pieced together some of the excess with a draw stitch so it covered the entire thing. With the moleskin laid over it, it feels perfectly smooth.

I then put a few staples loosely in each side of the board, and did a couple stitches through each, catching the felt to keep it firmly in place without stapling it directly. Then I hammered the staples in more firmly once the stitches were done. Neglected to take a photo of that part.

Then I took the legs off again so I could attached the moleskin. The cloth I used was fairly wide, so I cut the excess off and did a rolled hem on the raw edges to keep it from fraying. I then stapled it along just the top of the board (on the underside), stretched it up and over the top of the board, pulled it fairly tight and then did a few staples at the bottom of the board (again on the underside. Then I worked my way from end to end, putting in a few staples along the sides while pulling it tight, and then several more once everything was fixed into place.

After that the only thing to do was put these spring latches in place and drill a hole in the bottom of the foot for the latch to go into. This keeps the legs folded flat while the door is hanging or being moved until I'm ready to set it up.

An added bonus of this whole setup is that my cat now has a little fort to hang out in while I'm working:

Combined with my hideaway sewing desk, I feel like I now have a pretty solid setup going!

And thankfully, I have enough moleskin leftover to make some hams. Looking forward to tackling that next, then hopefully I'll be adequately equipped once my Purple Box arrives!

Thanks for everything you're doing Reza, and thanks for setting up this community! Looking forward to learning with/from everyone here.
