I do not have the time to make some for sale and its also not my "invention", just my idea of making some that fit my machines.
There are no limits, if my embroidery machine would have been placed the other way around I would have made a train engine cover for it and wagons for the other machines. Noahs ark was also an idea or a flowerbox with flowers and I would love to see what you come up with.
