Hi John, here in France, we call this pattern: "point of hungary"
Some years ago I had carpet in my bedroom, I removed it because my dog had deteriorated significantly. I have no dog today, maybe I defer carpet later. I just have a small rug at the foot of my bed, the hall of my entrance has marble but there is carpet on all other rooms. belive me, this is a real pleasure to clean all the carpets with Hoover convertible model 652. Born in 1959, my parents bought a first Hoover grey 652 in 1960, this one still works very well, my brother has recovered to his country house. Then we had a green 652A, we kept it until the maid broken it.
Today I own this small and humble collection of 7 blue Hoover 6525C plus an old 612.
Later, if I can find a green 652A I'll try to get it, it depends of the price, but after that, it would be good to stop my search, I have to watch my spending...
