Well you can't sew on the go with it (thats my next project to work on) but with summer coming here and also just wanting to stitch in bed or on the couch more easily I decided to make one of these trays. It's simply a square, lined with flannelette, with the corners sewn up. I had to unpick and resew the corners (so maybe tack them first until it stands the way you want it to) but it was super easy, made it to a nice small size I find convenient and now I just load my floss, needles, scissors etc in, and go sit outside or in bed and embroider. I hurt my back recently and was stuck in bed for 2 days, nearly went insane but this tray saved me!!
