I have designed a collection of almost 20 sweaters and vests in the past several years. The main thing that holds me back from publishing the patterns is resizing. The prototype for each garment fits a U.S. size 12 or 14 woman (me). My cousin Marilyn generously loaned me several books that help with stitch count and sizing. I can add, subtract, and figure gauge, but the complexity of this process is outside my realm of ability. Is there someone who could suggest something that would help me put the final polish on these patterns?
Knitting, writing and other joys 
Thanks for the comments. This really helps so I will forge ahead.
Sad to say I’ve no help to offer, but I’m a size 12-14 and I think most of the female population is as well. And if they aren’t, they know someone who is! I’d line up for the book without the sizes I wouldn’t knit anyway LOL! If you don’t figure out a better way, how about charging for PDF downloads of single patterns???
Katherine, why not join the Knitware Designers group on line and ask for their help. I know Joan Schrouder is in the group and would be so willing to help you. If you need her e-mail address just let me know.I’m sure many of them either use a design program or something like that. There is one for the Mac. I think Meg had it.
Lov u dear,

while she is over whelmed right now, (and might not share it even if she wasn’t) Anne Modisett uses an Excel spread sheet to scale up/down sizes–you might want to contact her, and ask if her spreadsheet is available. (for sale)
It’s not perfect, but (or rather getting perfect requires lots of ratio’s formulas) excel is one way to go.
if gauge is X and size 12 is a finished size of 20 inches, (and size 14 is 22, and 18 is 26..) and so on.. then the cast on is pretty easy to figure. (the cast on is Y stitches at X gauge =zz stitches)
the tricky formulas come with armhole/sleeve and Neck shaping.. (since a size 12 might become size 16 by adding 4 inches at hem (and bust) but you can’t just use the same formula (add 4 inches) for armhole shaping and neck shaping but if you can figure the ratio’s..
likewise, if there is a stitch pattern repeat, how to allow for X repeats (and making sure the repeats are centered)
but using excel would be easier than doing all the math your self
Bless you. The problem with a lot of my designs is that they have either texture or color-change stitch patterns that have a big repeat. It is kind of like hanging wallpaper that has a long repeat in order to match the next strip. Adding or deleting a whole repeat would increase or decrease it by several inches. That is why I’ve stuck with publishing mostly sock patterns.
Outside of sitting down and crunching numbers, getting the standard measurements for the different sizes and going from there… seems to me there might be some computer software *somewhere* to help with this? Seems to me I’ve run across just such a thing… I’ll try and clear some cobwebs and see what I can find.
