Pattern Description:

A circular vest with a large lace shawl collar.
This one piece seamless vest works up quickly on size 15 needles.
(I made my 3rd one in 4 days!)
Lots of interesting techniques to keep you interested and enough instruction to teach you the techniques if you don't already know them.
Best of all, there are not seams to sew, only ends to weave in.

Construction notes: The back is worked flat from the top. At the bottom edge, short rows are worked for shaping and stitches are left live. The lacework is knit in one piece in the round, starting with the live stitches at the bottom, casting on stitches for the armhole, picking up stitches along the top cast on edge and casting on stitches for the second armhole. The piece is finished with an I-cord bind off. No seams to sew.

Pattern notes: The lace work is very simple. The stitch pattern changes often to accommodate increasing, therefore the directions are written row by row and there is no chart. There are only 26 (28, 30, 32, 34) rounds of lace.

My design philosophy: My designs are a mixture of traditional and non-traditional elements. My patterns are easy to read and are often based on simple shapes and techniques that minimize complicated finishing. The majority of my patterns are accessories so sizing is often not critical. My love of texture and color shows up in my ability to mix yarns and to match yarns to particular styles.
