Heaven, those are beautiful. I have never seen a pine cone that huge. It's a decoration all by itself with a bit of glitter and a bow. Love it.
Those big sugar pine cones were around $2.99 at Super Store a couple years back. Michaels might have them as well. They are quite beautiful when some pretty ribbon and a few other little sprigs (like dried berries or fruit, some birch bark curls, etc) are added. Your local nursery may have them as well.
The ones I made I painted the tips of the cones with white paint to make it look like they had snow on them.
I want to post pictures of all my X-mas decor but have to figure that out yet. Hubby can take the pics with the blackberry but how I get them from there to here is the confusing part.
You'll need to upload the images to an online photo sharing account like Photobucket. Then you can link to them from here.
