Knit 2 Socks in 1 presents a fresh technique designed to help knitters avoid the dreaded “single-sock syndrome” — losing interest or momentum after finishing the first sock. 
 
Instead of knitting two separate socks (or juggling two pieces at once), Talley’s method has you knit one continuous tube (which forms both socks) and then split it using lifelines (i.e. scrap yarn threaded through stitches) to separate the socks at the appropriate point.
The heels and toes are worked with a simple two-row repeat, and the finish uses a “hat closure” approach (a technique more commonly used to close tops of hats) for ease and elegance. 
Key Features
 
Accessible technique for many levels — The method is pitched as being usable by sock knitters of all levels, making the “two at one” approach more approachable than many fancy or complicated dual sock methods. 
Customizability — You can use whatever yarn, gauge, and needles you like; the book supports customisation. 
Many design options — The book includes 21 different sock style variations (across levels of difficulty, styles, stitch patterns, sizes from child to adult), so knitters can pick from many endings. 
No turning heels or Kitchener stitch required — The method is built to simplify what many knitters find challenging about socks (heel turns, grafting, etc.). 
Guidance, charts & planning tools — The book offers clear instructions, charts, and supports planning via worksheets (e.g. to figure out sizing and gauge) to adapt the method to your yarn and preferences.
