I have also decided that my bamboo dpns are too dull for this project (I know I am half done and I am deciding this). I actually decided it a long time ago but have not had an opportunity to go get another set of needles. The k2tbl which feature prominately in this pattern needs a sharp needle - so does the purl tbl.
This delay will be good so I finish Ali's socks before I finish knitting myself another pair. It will help me finish a project. I only have about 5 cm left of knitting on Ali's socks so it shouldn't take too long. Just depends on how much time I have for knitting this week.
