Two black fish are ready to be felted. Right below them is a yellow fish still in progress. The fins on the fishes sides are 3-D. By shading the wool fibers from lighter bellies to darker on the top side, the fish look more realistic.
Here is another block that may become part of the group above, or it may be a little quilt as it is. The orange seaweed is wool yarn that I've couched with different shades of pearl cotton thread. The star fish has beads radiating from the center. I see the blue parrotfish needs to get an embroidered gill. The fishes eyes are beads.
