First of all don't overload your roller. secondly make sure that the roller is not worn or was badly cleaned the last time it was used. and last and very important once the paint has been evened out on the wall lightly feather it with the roller don't press too hard on it.
To make solid colored paint keep stirring until the marbleized effect stops. Make sure to get all sides and the bottom as well.

Cans or buckets that you keep paint in.
Roller skating can keep you fit if you do it regularly. I am a roller skater and I have not been in better shape and I have now met great people at our rink and I now compete with them. We all get along in our club!!

Both are just as good as each other if you get the more exspensive brands, quite often cheap markers are not very good, but as long as you keep the fabric tight it should be fine. personally I prefer fabric paint but either will do. Including fabric pastells If you are working on a small item or want to do detail work, a good set of fabric markers are invaluable. Their down side is the smaller number of colours available. With fabric paints you can cover a larger area with less work, They come in a wide selection of colours and being able to mix colours gives you much more flexibility.
