You can take these six pre-cut trees out of the card easily, squeeze the middle part and this way you create a lovely 3D gift label! The good thing is: the tree doesn’t have a perforation hole, you can just slide the ribbon through the tree itself. By stringing several trees on a cord, you create a cheerful Christmas garland.
My best DIY tip though is the homemade Christmas card: buy nice thick A4 paper in a colour that matches the trees and cut it to size. Or make the project even easier with ready-made coloured greeting cards without print, (eg from Papercard). Glue a tree on the front and your homemade 3D Christmas card is ready!
