This has been going all year, but I just came across it via NOTCOT:
Colleen Baran's Ring a Day project is one surprisingly creative treat after another. The project is about ideas and fun more then commercial work. It's about the idea that feels most exciting that day. Some rings will be ephemeral and temporary made of fragile materials.
Others will be carefully crafted for durability and meant for long term daily wear. These will be coming later in the year.
They are experiments in line, shape & color. An exploration of ideas like a daily sketchbook.
Some are quite serious and carefully planned, some are a little silly, some will take a couple minutes, others many, many hours.
Most (so far) are made of recycled or alternative materials as diverse as felt, false eyelashes, cucumber facemasks, lipstick, repurposed elastic bands, twist ties, straws and tinfoil with carob.
The rings are documented on Flickr - my favourite so far is the straw ring illustrated below.
