My S16 sits there in all her nakedness!
Unless my machines are packed away, I do not cover them.
If you're wanting to cover yours, you could make a cover easy enough.
Perhaps orphan blocks? Or a quilt? Or a leader/ender project til you have enough?
I'd just fold in 1/2 for a flat sleeve and then do boxed corners.
Would take some measuring to make sure you had the right size needed.
Maybe add pockets on the side, to hold rulers/tools you use only with the machine?
Now you have me thinking ... perhaps I should spiff mine up, using a flimsy that has no specific destiny at this time! What better way than for me to keep enjoying that flimsy. All.By.Myself!
