I saw this idea when I was shopping last Christmas. I took a picture with every intention of making them last year. Here we are a year later and I can finally delete the photo reminder.
These are made from a tree branch from our yard. My husband cut these up into disks years ago after drying the branch for months. My son and I drew snowflakes on the wood discs and I drilled many, many holes. We sewed the snowflakes with red twine (from the dollar store) using a large needle. Then screwed hooks and added twine to hang them on the tree.
