These are the rest of the swaps I've done:
Hedgehogs, Gnomes, and Mushrooms - Embroidered Cloth Covered Buttons
     - Metal button
     - Cotton muslin
     - Cotton embroidery thread
These scenes are all from Jan Brett's book Hedgie's Surprise, and I included a small coloring book printed from her website for extra hedgehog fun.

Summer Nature Table - Needle Felted Hermit Crabs and Shell Babies
    - Wool
    - Shell
    - Drift wood from Alki Beach
     
      
  
Rainbows - Mini Mobile
       - Glass beads
       - Metal (can't remember exactly what)
I made two versions of this, pastel and bright. Sadly, none of the photos of the brights turned out even this well.     

  
Just For Moms - Necklaces (using a wire jig)
       - Silk ribbon
       - Metal (again unknown)
       - Glass bead
    

  
Autumn Nature Table - Dreamcatchers
       - Metal ring
       - Leather
       - Glass beads
       - Cotton thread
    

  
Bath - Felted Soap
      - Wool
      - Trader Joe's Bar Soap  
I will never do this again. I pretty much hated every moment of it, even once I got it working (I actually called Weaving Works part way through to make sure I hadn't accidentally purchased machine washable roving). I have wet felted before and enjoyed it, and have done a lot of needle felting and like it. I did not like wet felting or needle felting on soap. And the red/orange/yellow squashed octopus? That was supposed to be my amazing fiery sun.
