I made a huge shawl or medium blanket out of sock yarn that was left over from other projects. The finished blocked size is 72 inches. I used a 5 mm needle and started in the centre with dpn's. When I ran out of one colour I just added another by knitting the two together for 10 stitches and after it was blocked I cut the ends off.
Several months ago I bought s book called Two-ende Knitting by Anne - Maj Ling. This is a traditional Scandinavian Technique - Tvaandssticking also known as Twined Knitting or TWo-end Knitting. You can check out her designs on revelry. I was curious if any of my bro's out there have tried this technique? Let me know.
