I got some samples awhile ago of these swabs. http://www.superbrush.com/
They are these little foamy swabs that kind of look like the things you use to put on eyeshadow. I do like them a lot though. They work really well in small applications. They don't fall apart and you can wash them a few times before having to toss them - if you remember to wash the paint off right away, that is. I am notorious for leaving paint on brushes and then having it dried up and impossible to get off.
I recently had to get into some small areas on my polymer clay stuff. The swabs worked great in that application. They are also good for chalk ink. I did some small stuff like ATCs and inchies and they were much easier to use than the detail brushes I have. They are easier for me to control.
I am not sure where to get them retail. They are also used in other applications. So, don't forget to look around the next time you have a doctor's or dentist's appt.
OT: I saw these huge-O cotton swabs - like the ones you use for your ears - at a recent doctor's visit. I asked and snagged a couple. Looks like a big white match to me. Don't have a clue what I will ever do with it. I just had to have it. You understand that, don't you?
