This is something I have been meaning to do for several years. I finally, finally got around to making some longies to sell over on etsy. I'm always so uncomfortable putting a price on my work, but I do feel that these are very well made, and they do take a really, really long time to knit up due to the tight gauge of the waistband and upper hip (US 3 and 5 needles = slow).
So there they are, one newborn pair. I can take a limited number of custom orders for these (in a range of sizes), so if you know anyone looking for longies made with love and care...check 'em out!
