Also not an amigurumi, but I wanted to make my own version of the Artfully Simple Infinity Scarf by Moogly
Here is the result:
The yarn I used was a leftover over of Rio (Lammy, the green/blue/white) and about 1.5 skeins of Scheepjes Larra Batik 7501 S2 (light and dark green and light and dark blue). Both yarns used are cotton, hook 2.5.
