The Lati Dress by Shelley Selwood is one of the first patterns I actually got to grips with and I learnt lots from it. I still have the occasional phase of knitting this pattern simply because it is easy & very familiar.
And yep, it's a lati top but this does fit Blythe and actually makes a really nice t-shirt or dress with minimal alteration.
Tools/Yarn needed: You are supposed to use 4ply and 2.25mm needles but I admit that I have used a variety of different wool/needle sizes as I don't have that many colours of 4ply yet. In normal double knit this pattern can turn out a little bit baggy but that's fine if you're after a baggy fit. I have knit this in King Cole Haze DK and it turned out beautifully, using size 11 needles (can't remember the metric size!)
Skills needed: Increasing and Seed stitch. I say seed stitch is a skill because I still forget how to do it midway through a row and end up with Rib. It drives me mad!
Other notes: I don't bother with markers as I don't see the point. I wrote this out without markers so if anyone would like me to write out what I do on here feel free to ask. To make a dress you can simply knit this longer and if you are feeling very adventurous you can do the skirt bit in a different stitch!
