Can't decide what to try or just need a small length to verify compatibility? Save on shipping and try more before committing to a spool!  50g coils are now available directly on the product pages.  This is about 15m for 1.75mm diameter and 5m for 2.85mm diameter except Iron and Steel which are about 10m and 7m for 1.75mm and 3m and 4m for 2.85mm. in any case, 50g is enough for a gnome or two.
