This is a great pattern for a quick and relatively easy ornament set which would be especially great for quick gifts, or craft fairs. The fact that they are quick to make does not mean that they don’t look great though and they may find their way to your own tree. The most challenging part of the whole design might just be they tying of the thread which is not that difficult either if you give yourself enough thread to work with.
The inner ornaments could also be used on their own as mini-ornaments for a small tree, as charms for hanging on gifts or even as fridge magnets. While being fairly easy and quick, this pattern may not be suitable for a scroll saw novice.
