First off, the finished project:
These birds are cotton fabric with 2 layers of fleece in between to give them more "body." I drew a bird shape, then zig-zag stitched all around, then cut out the finished "quilted" bird:
The hard part was getting them lined up on the strings, and then sewing them onto the strings so they would hang straight:
I used embroidery floss and beads to attach the birds.
I stuck the needle up from the bottom of the bird, between the fleece layers so you couldn't see the string. It went in the bottom and out the top. To find these spots, I stuck a needle through the top, near the middle and then let the string dangle. This is where the top and bottom insertion points would be. (Does that make sense?)
Then, I just tied the strings to a wooden embroidery hoop, and covered the hoop with left-over scraps from the birds.
Whew! It took a while, but I think it was worth it in the end!
Let me know if you have questions.
