My sewing machine is in the balcony along with some cabinet pieces that belong to my landlord. Two of them piled up make a great ironing-board height, so I decided to give one of them a temporary ironing-board top.
I took on old mattress protector for batting, an old thick cotton sheet for covering and with the help of Velcro strips I put my temporary ironing-board top together - and I love the result (I keep petting it when I pass it. I better stop that)! And it's totally removable (and washable. and does not jeopardize my deposit).
Here's how I made it.
