Good luck with it all! Love you Twister table-runner from your last post; one day I`ll buy that spesific ruler :-)
You will love the ruler. And if you watch you can find some cheater cloth that is nothing but patchwork squares you just have to add border and then cut. It is nice and not at all bumpy so you can use it on a table and set a vase on it and not have to worry about spills.
