My wife made several amigirumi Star Wars characters for a mobile for our soon-to-be-born grandson. Princess Leia, Yoda, R2D2 and Chewbacca, with the Millenium Falcon as the center piece. My job was to assemble the mobile. To that end, in addition to the amigirumi, I used an 8" embroidery hoop, a 2" welded steel ring, 20 lb fishing line, a hot glue gun, a drill (I used my Dremel) and a needle with an eye large enough to fit the fishing line through.
This Instructable will show you how to build the framework, attach the figures and make everything level. My wife crocheted the figures and created a cover to hide the hardware that's not covered here.
Step 1: Drill Holes
The first step is to drill four holes in the embroidery hoop. These will be the attachment points for the mobile. Cinch the ring tight before drilling.
Step 2: Add the Falcon
Cut two equal length pieces of fishing line. Take the first and sew one end into the Millennium Falcon at one corner. Run the line through one of the holes in the embroidery hoop and through the opposite side hole. See the other end into the diagonal opposite where the first line was sewn. Repeat for the other side. Stringing it this way will provide some easy leveling capability and proved much easier than doing separate strings for each corner. Once you have it level, use tape to temporarily secure the line so it doesn't move.
Step 3: Add Top Ring
Cut two, 18" lengths of fishing line. Tie one into the embroidery hoop, run through the 2" ring and then tie the other end into the next hole in the embroidery hoop counterclockwise.
Step 4: Add Other Figures
Sew a length of fishing line through the head of all of the figures. Tie them into holes in the embroidery hoop. If the figures are of differing weights, balance the heavier objects opposite each other.
Step 5: Adjust the Mobile
Hang the mobile from a hook and gently pull the strings attached to the Falcon and those attaching the hoop to the top until everything appears centered and level.
Step 6: Glue Strings in Place
Use the hot glue gun to secure the fishing line to the embroidery hoop. Also glue the fishing line where it attaches to the 2" ring.
