How many skeins will I need for a sweater?

As a shop owner, how many times have I been asked this question? Many!! 

This guide will help them determine how much to buy. Stashbot will pay for itself over and over as it saves knitters from purchasing more skeins of yarn than they need (or be disappointed in not having enough for the pattern you end up falling in love with!!). In addition to yarn requirements, Stashbot includes an article by Hannah on stash psychology with tips on how knitters can change their stash for the better.
