Here is a project I made for one of my classes this semester (I'm an apparel design master's student). I made about 8 knitted strips (like lots of scarves; all my pieces were rectangular) of different lengths and widths (ranging from about 18" long to 4.5' long). I made sure to make two identical pieces that were the proper length and width for sleeves, and two identical pieces for the sides of the bodice area. Then I draped all the pieces on my dress form and whip-stitched them together with yarn.
***It's been a while since I've checked my stuff on Craftster, and I just thought I would pop in and take a peek at my old stuff. I was so excited when all saw all of your responses wanting a tutorial on the scarf sweater and wanting to see more of my stuff. I have been very busy lately with work and school (yes, I'm taking more classes even though I already have a degree. why? because I want to be in school the rest of my life), but I have a bit of a break coming up, so then I will make a tutorial. I think most of you will be surprised to find that making this sweater is easier than you think, but still will take a good amount of time (unless you cheat like me and make your scarves on a manual knitting machine). Also, I will try to get together pictures of my other work for everyone to see, which you will discover is very random, concerning both subject and medium.***
