Last night I added seaweed as the finishing touches to the mermaid piece on which I have been working. Here I used two layers of batting to puff up the shell and pink seed beads to suggest a string of pearls. The seaweed is three strands of embroidery floss and some blue/green eyelash yarn.
A couple of years ago, I purchased a bag of twisted yarn pieces thinking I would be able to use it in my art quilts. I cut a few short sections to create some different textured seaweed. I've included this enlarged photo to show how I beaded the floss seaweed. At this point, this piece just needs to be quilted.
