The trick is to add a touch or two which brings them to another level. It is also important to make them a bit more nicely than a ten-year-old might make them.
I have fun when I am bored with my own pattern collection by going to the gazillion sites online loaded with craft ideas for kids. Oh, sure, I bypass dozens of those projects as not what I want. But I always find a few, each time, which I save or print.
There is an added benefit to this goldmine of ideas: these projects are always easy to make. With the holiday crafting season hot on our minds, it is a good time to go hunting for a fresh, new gift idea.
