I like the look but I'm usually too chicken to stamp directly on my layout or card because I'm not that good at it and I'm afraid of messing up my project. If I stamp, usually it's on a journaling card or something that I'm adding to the project and can be taken off if I make an error.
you would think that I would considering all the stamps I have bought over the years. However they are still sitting in a cupboard and now I am getting rid of many. I use a few but they are few and far between.
I'm not much of a stamper. I used to have tons of them but they all went to a good home. I just have a few now that I use rarely. When I do use them it is usually stamping directly on my project. Sometimes it turns out and sometimes it gets covered up. The unknown is part of the fun.
