Well, I have been ruminating for some time on a way to make a Dandelion since I heartily agree with the idea of using it as an Xmarks plant badge.

When I was buying some lovely new wooly jumpers (Sweaters) from the Marie Curie cancer care store I noticed they were selling their Daffodil pins.

I bought two and headed home with an idea forming.

I took the fabric from both of them and cut it to form circles. Then I cut them to resemble dandelion petals and layered all four of them on to one pin.
After that I removed the badge pin and replaced it with a rare earth magnet.
Here are a few pictures of it taken tonight.
(I am working on making some leaves to go with it.)
