Gauge and yarn substitution
I found a yarn I love but the gauge is about half for the pattern. Can I double the number of stitches? It is a baby sweater in stockinette, basically and if the gauge is 4 sts-in and I get 8 sts-in, the pattern calls to cast on 45 can I just cast on 90?
or i could double strand and get closer- 5 sts-in. which one would be better? thanks
