I got an embroidery machine a few weeks ago, and it's main use is for adding interest to plain fabrics/garments - I'm doing a great line in stylish fleece jackets currently.
I'm really wanting to try FSL, mainly for things like Christmas decorations, I've downloaded lots of designs, but I'm too busy to actually try any.
I got a Janome 350e, as it was a balance between price and hoop size. You may think you only want to do small FSL, but you may easily get sidetracked when you start looking at embroidery design websites...
My avatar is a machine embroidered design on a hi-vis flag I made for a friend's recumbent trike - see, the possibilities are endless :-)
