Well, I have acquired thirteen brushes and I have eleven more on their way. I purchased them through Ebay. I haven't looked in any antique stores or estate sales. I looked at Etsy and liked many of the brushes I saw. Many were in pristine condition and a little spendy. I think I am done for awhile I have to figure out what to do with these. I think the Dremel will become a reality. What is brush lust?
