You've got to check this out! It's something I've just come across online and I think I'll order one for my nursery, another for my living room, and maybe one for the kitchen too!
There are a couple of other companies that make and market these but this one;
The Painted House - patterned paint rollers!
seems to have good quality, or even the same patterns, for the best price. You do pay more for shipping though since it comes from the UK.
Just go see if it's not worth it!
Ps, the house next door goes up for sale tomorrow!!! Won't you be my neighbor??
