I knitted this up for my grandson (who is growing faster than expected) This is super easy and was a quick knit for me. The pattern calls for a certain yardage but I found that with an 18 month old size I was able to use less than 2 skeins of Lorna's Laces worsted for the body and sleeves (I omitted the hood & knit in the optional neckband - instructions included in pattern) and another LL contrasting nearly solid for the ribbing, neckband, cuffs and front bands with plenty of that leftover for a matching hat in the solid color. I love how this pattern is simple enough so you can add your own special touches (patterned knitting, stripes, etc) if you want to. I plan to make several others of this sweater so my grandson will have a nice wardrobe of sweaters this fall and winter. This pattern gives directions for 6 months to 18 months sizes. I have other Knitting Pure & Simple patterns - and love them all - you really can't go wrong with any of them or the Lorna's Laces yarn either!!
