DISCLAIMER: The instructions below are only informative guidelines. You may try to use them to achieve the result similar to Lace Cardigan featured in VK. Be aware that these were NOT tech edited and have not been test knitted. Some measurements may differ because your row gauge may be different, so you may need to make changes to fit it to your body measurements.
I'd tried to calculate the measurements to best of my abilities, but since your row gauge might (and most likely will) be different, I'd recommend to make the sleeves first, since they are going to be slightly wider than in the pattern (see the schematics below). Then when you make the body, adjust the underarms height so that you can fit the sleeve caps in comfortably.
To achieve following sizes, you should work it in the gauges (# sts = 4") as you can see below.
|SIZE (inches)||36 3/4||37 1/2||39 1/2||41 3/4||44||46 3/4|
|Waterfall patt (# sts = 4")||21||20||19||18||17||16|
|Lace patt (# sts = 4")||24||23||22||20.5||19.5||18|
You should get following measurements for the sizes as you can see in the schematics (click to enlarge them):
To achieve the measurements in the schematics, I made a few modifications to original pattern.
Under RIBBED WAIST: .... work in k3, p3 rib for "3 1/4, 3 1/4, 3 1/4, 3 1/2, 3 3/4, 4)", .... Then work in waterfall patt for (5 1/2, 5 1/2, 5 1/2, 5 1/2, 5 1/2, 5 3/4)".
Under BACK: ..... bind off for armhole as written in the pattern; then work even until armhole measures (6 1/2, 7, 7 1/4, 7 3/4, 8, 8 1/2)". (then work neck and shoulder shaping.)
Under FRONT: .... work underarm shaping as written in the pattern; AT THE SAME TIME, after underarm measures (1/4, 3/4, 1, 1 1/2, 1 3/4, 2 1/4)", from the neck edge bind off .... (work the front neck shaping)
If you have any suggestions or changes that might help others to make this cardi in the larger size, please let me know. I hope these basic guidelines will help you to work your size successfully.
