When I lived in a small apartment I had two stacks of two tucker totes (all four the same style, twoshorter ones on top of two bigger ones) within close proximity of each other and took a smooth (garage sale) door and laid it on top for a table top. I would remove the door when I needed in the totes, put a towel on the door to iron, or sit and sew. (I even set my lamps on top of them for lighting. I didn't have much but made the best of what I had.)

Check out My Sewing Space thread in this section of QB. She moved into her daughter's room after she left home. She has a link to her blog where she has pictures

I use the kitchen floor tiles to square up my quilts since they're one foot square. I make the layer sandwich on the kitchen floor and slide the cutting mat under it, kind of matching one edge of the mat to a line on the floor... very handy. I sometimes tape the backing to the floor to keep it flat while placing the batting. Also do my safety pinning and basting while it's on the floor.
I keep most of my quilting supplies in a laundry basket and schlepp it off to the church quilting ministry every week. That way I can toss in some fabric or a WIP or 2, camera, magazines, and so on.

I am blessed with a nice quilt room now, but a few years ago I spent 3 years in a 5th wheel travel trailer while I took care of my FIL and his farm until his death.
I did some blog posts on some of the ideas I came up with and will add links below.

If any of you have seen Paula Nadelstern's books or award winning quilts, remember that she has a tiny New York apartment and does all her piecing on the kitchen table using a featherweight. Or did, she may have moved by now. But that is proof all the room in the world won't make you a good quilter, but time and attention to detail will.

a failed working wall idea

I don't see a photo of it but what worked well in the end was covering a long old fashioned roller shade with flannel and attaching it on my highest wall, which is where the little stair way is. Easy peasy out of the way when not in use.

Best wishes on what works out for you!

I sew in a small 2berth caravan. I purchased a small folding table to put the sewing machine on. Cutting and sandwiching I do on the very large 6 ft table which came with the van. This I have been known to use outside. This generates many exciting conversations. I could cut on the table inside or on a work surface if it rained.
