I started making them about 3 years again, when I could not find anything cute for my baby girl, on ebay in the us I saw all these bows that they make. I purchased a few really bad instruction that got me started. I also use Devons TNT templates and I love them, they are easy to use and all bows look the same.
There are a few free instructions around and if you purchase some, most of them have yahoo groups that you can join and some of those ladies are so fill of information.
I'm not making a lot at the moment as I am moving and have the house on the market, but I still have a list of people who want Christmas bows, and mothers at my sons school, always asking so I'm still funding my ribbon habit.
