This is an easy way to have simple ornaments that will fill your tree nicely. Collect pine cones. It doesn’t matter if they are evenly open or not. Put them on a cookie sheet and put them in the oven at low temp., probably around 250 degrees. You will hear some popping sound–but don’t be alarmed! When you take them out, they will all be dry and open evenly. I just take some small eye screws and screw them into the base of the pine cones and use string or ribbon to hang them on your tree.
