Pour ½ Cup of cold water into a large microwave safe bowl.
Add gelatin to bowl.
In a sauce pan, boil ½ Cup of water and pour over gelatin.
Stir until gelatin is completely dissolved.
Add corn syrup and stir until well mixed.
Add birdseed and stir until completely combined.
Place bowl in refrigerator for 10-15 minutes until gelatin begins to thicken.
**If gelatin no longer appears to be a thick liquid and starts to "set" then you have refrigerated it too long. Microwave the mixture 10-20 seconds to melt the gelatin and stir. Refrigerate the mixture for another 10-15 minutes.
Choose cookie cutters that you want to use to shape your ornaments and place on a parchment lined tray. (You'll need approximately 7-12 cookie cutters depending on their size.)
Cut 2-3 plastic drinking straws about 3" high.
Spoon birdseed mixture into cookie cutters and fill to the top. Place one straw into each cookie cutter about 1/2 inch from the edge. Press mixture with your fingers or a spoon to fill in the gaps.
Place ornaments in refrigerator overnight until gel has set.
Remove ornaments from cookie cutters by gently pushing them out. They should come out easily. Remove straws the same way.
Run a piece of twine through the hole and tie a knot at the top. Hang birdseed ornaments from tree branches.
