Introducing these very cute 10gm /42m mini Opal self-patterning 4ply sock or general purpose yarn.
Machine washable in cool water.  
Recommended needles 2 5mm - 3.25mm. 
This yarn is constructed of 75% Virgin wool plus 25% polyamid.  This Opal yarn is just the same high quality as the 100% balls of self-patterning yarn listed on this website.
This blend gives warmth, elasticity, and durability, as well as moisture wicking properties.
Each pack of 28 mini balls are randomly packaged by Opal.  Each pack is unique.  The two photos are a reasonable indication of the range that is in a pack, but Opal doesn't guarantee that individual colours will be in each pack.
28 x 10gm balls = 280gms/1176m 
Use them in striped unique socks or for the toes, heels, and cuffs.  Make a striped blanket or shawl using a plan colour in between the different patterned yarn.  Knit or crochet up some squares, and use a plan colour to join them with.  You are only limited by your creativity.  What would you make?
