Gosh this stuff's nice. Just what it says on the label - organic cotton aran.
Each barrel (that's what Rico call the balls, isn't it a great name?) contains approximatley 90m/50g and can be washed in the machine on a gentle 40 degree wash.
It's a standard aran so can be used for any aran pattern although please check your tension and bear in mind that cotton tends to "give" a bit with wear - many aran patterns will be made with wool which is bouncier. There are a couple of patterns that are specific to this yarn, find them over in the "Patterns" section
There is nothing not to like about this yarn!
