This pattern is knitted in the round using circular needles from the bottom up, so no side seams! And the garment is knitted in one piece. The only seams are at the shoulder. Two colors are used. For the smallest size, one skein is used for the bodice color and two skeins for the main body. For the largest, two skeins for the bodice and three for the body. The yarn used is a new one for Scarlet Fleece. It is a light weight silk noil yarn that wears like a fluffy cotton. This fiber is so comfortable to wear, enjoy!
