If you want a simple project using this lovely Gotland DK yarn, how about a pair of handwarmers?  I found it used just over 25g so we have made up kits of the right amount of yarn and provide  the pattern. It makes a lovely gift to a knitter friend too.   This kit comes with a pair of 4mm straight knitting needles.
 
Gotland sheep produce very fine and particularly warm wool in shades from silver to charcoal – the only sheep that produce a truly grey fleece. The resulting yarn has a wonderful lustre, takes dye beautifully and knits up to produce a remarkably light fabric.
