I'm looking to knit the Mommy Snug from the summer 2006 Interweave Knits. I haven't ever knit an adult garment before, and don't really have any experience knitting with cottons. The pattern calls for Gedifra Cotton Merino (50/50 cotton/wool) that I've heard is anywhere from a DK to aran weight. I've found Classic Elite Four Seasons Cotton (70 cotton/30 wool) which is somewhere in the worsted/aran range.
Gauge for the Gedifra is 17st/4" on US 9s. Gauge for the Classic Elite is 18st/4" on US 8s. The pattern designer seems to think the Gedifra guage is a bit too loose, and she prefers it on 8s.
Any thoughts on whether this would be a good substitute or whether any other yarns might work better? Or even what to look for when trying to find a subsitute?
I don't want the finished sweater to be too heavy, and I'm hoping to wear it in the summer and fall, if that helps at all.
