I started knitting with Ribbon this year also.
Here are two summer tops which I made from Ribbon
The sleeveless top is my own design made with nylon Crystal Palace Deco Stardust Ribbon in Aqua. This project was a nightmare. I did not wash my swatch before knitting the tank and it shrunk during my first day wearing it to the office. I had no idea that it would shrink when wet. Glad that I was wearing a jacket! Any way, I picked up along the bottom and added 3 rows of Garter Stitch and a few sections of Drop Stitch and I think it still looks pretty good…
This other top, is made with cotton Schachenmayr Nomotta Scaletta from Inspiration 75. The pattern is actually designed for long sleeve, however, I wanted to wear it under a jacket for the office. This Cotton Railroad ribbon is really soft and currently discontinued. I bought a ton of it in 3 different colors from Elann.com a while ago.
I have aquired lots of ribbon yarns in my stash and I have been frustrated with how few good books are out there with Garment patterns for ribbon yarns. Usually I see poncho, shawls and bag patterns. Ribbon Knits by Judi Alweil has some nice sweaters I might actually feel confortable wearing to the office! Other patterns for Colinette Giotto are nice also.
