Socks!

Hey all! My friend has asked me to knit her some knee high socks from a certain pattern. The problem is the socks pattern only goes up to a US size 7 and her foot size is a 12. How would I go about utilizing the pattern but getting her sick size ? I’ve never knitted socks before so any help would be great. Thank you!

Please link to the pattern selected. It may be a fairly simple solution or it may be very difficult.

If you’ve never done socks before I suggest that you download Lifestyle Toe Up Socks - No Swatch Needed and make yourself a pair in worsted weight yarn to learn a few things about sock knitting. You’ll have a nice pair of slipper socks for your efforts. Fitting socks is about foot width at least as much as it is about length, and determining what style of heel will fit.
