So I am finally taking the step to a simple fair isle project and want to go to WEBS this weekend for the yarn. Question is, the pattern calls for a DK weight (it is vintage 1948 sweater vest/cardigan set). Does the yarn have to be "stiff" (like Lopi) or could I use the new Berroco Ultra Alpaca 50% alpaca/50% wool? It's a beautiful yarn but from what I have been reading, might it be too soft for stitch definition? No steaks involved in this pattern (front/back/2 sleeves).
Can any of you accomplished guys help me please?
