I think this is just the cutest thing.
Here's my version:
I think this would be a great gift for someone who doesn't really sew. If you used a larger jar (say, a pint) you could fit a little pair of scissors in there, and the recipient would have everything they need to mend a tear or sew on a button.
For a quilter, maybe fill the whole bottom with quilting pins (because I think you use a lot when you quilt, not that I know from experience just yet) or safety pins. Make sure, though - I'm just guessing.
For someone new to sewing, you could use a big jar and put a whole project in there! (Maybe instructions and materials for a sock monkey?) I think the possibilities are endless.
I used an older wide-mouth half pint jar for mine, filled with a few notions.
All I know is that this was really easy, fun, and I really like it. I want to make more, so maybe I will. Then again, I saw this Sushi Pin Cushion, and this Cactus One...
