Knitting/crocheting within a Collection has always drawn me in. I like to purchase at least 500 gm of a yarn and then challenge myself as to what can be made. If my aim is garments, I often purchase 2 to 3 lb. (1500 gm) or more. Not necessarily the same colour, but often the same yarn.
These photos are a variety of items from 500 gm acrylic/wool mix.

The last photo is a TIP, the use of markers that indicate the increase rows until the centre of the earwarmer which is the Blue Marker, and then the reverse decreases.
