My brother 6000 didn't have a cover so I used her to make her one. I sewed a bunch of 4 1/2 inch square that I had cut and sewed them together and made a quilt sandwich out of it.
I used muslin for the back and poly as battening. Don't want any dust to get to her workings.
Measured the side and subtracted 3 inches for the top and divided it in half and cut some thick fabric for the sides and sewed them on. I had some blanket binding so i banded it with that for the binding.
Just right! Great use of scrap fabric
Next i need to make her a mat!
Have a good one
