There are not many GT spread cloths for sale online and it seems most people make their own as they tend to be expensive. So, I made my own I actually love it, I think my cards do too. It was so easy to make it took me maybe one hour at most. The best thing is I don't have count the houses I just move the card.
I measured my fabric cut it and sewed two pieces together. Then I cut a piece of cardboard to the size of my cards. And used this to mark the houses with on fabric. I labeled each house with name and card number.
This makes reading GT so much easier.
