I do medieval re-enacting, so I'm constantly full of projects. I make all of mine and my husband's medieval clothes (also his 18th century clothes as well), and I make many of my clothes for work too.
I finished a little sampler embroidery this week that I started on in a class last weekend. It was raised Elizabethan embroidery. I had been wondering how people did stuffed or raised embroidery, and now I know. I'm just putting the final touches on a cloth belt that has couching embroidery on it. Sunday I am going to get started on making my husband some peasant clothing (he insists on having them! Normally I make him high-end clothing, but he says he can't work in that when he needs to work).
I have a serger, but the smallest serge I seem capable of putting on it is 1/4" wide. This is what I use for everything I sew. However, I am interested in the serged decorative edges you see on napkins and things like that that is teeny-tiny. As in a millimeter or two wide. My grandmother was showing me some curtains her sister-in-law made for her, and they were all edged like this, so I know there's a machine for home sewing that will do it, but I don't know what to look for.
