Pattern: Heartbeat Sweater by Jill Vosburg
Made for: me
Size: 44" bust with side panel modifications
Needle: US 5 (back panel), US 3 (front panel), US 2 (side panels, sleeves, neckline)
Yarn: mercerized cotton
Colorway: purple and pink varigated (front/back panels), purple (side panels, sleeves, neckline)
I got the yarn in a swap. (Waves to punkmom
The pattern goes up to a 64" bust, but as written it isn't all that well designed to accommodate larger sizes - the shoulders and neckline end up too wide. Also the side panel width doesn't change (but I think that it should—a person who is bigger around also tends to have wider sides).
We did it as a KAL on the ample-knitters
yahoo group. Different folks modified the pattern in different ways to address these issues.
My bust is larger than the 44" size I knit; I made up the difference by increasing the width of the side panels. Also I modified the triangles at the bottom of the back sweater panel to accommodate wider hips. (I won't do that again if I make another Heartbeat Sweater, because it makes the bottom of the sweater into an upside-down vee shape, which isn't entirely flattering. But it looks OK for this one).
I used #5 needles and continental knitting for the first front/back panel, but the fabric was too loose. I switched to #3 needles and combination knitting for the second front/back panel. When I was ready to start the sleeves, side panels, and neckline I discovered the purple yarn was much thinner than the multicolored yarn, so I knit with two strands held together on #2 needles.
The sweater is loose on me - my gauge-fu for garments larger than socks or hats is weak (and it doesn't help when I change techniques and needle sizes mid-project). It has some drape so it looks OK at this size, but I may take in the side panels at some point.
Better pictures to come. I've mislaid my camera so I took this on my crappy cellphone camera. It's a detail of the front panel and neckline. ( stitches )
