On my last vacation I found a pretty nice yarn store in Deventer which had a great selection of Aade Long yarns.
I love those long gradient wool yarns

Both skeins are about 1.000 m, so quite a bit. I would like to make something in stranded colorwork with both colors running against each other - I think they will look great that way
Not sure what exactly it will be, a second layer garment most likely.
