Lion Brand Yarn's apple.
When I was on lionbrand.com (this site is great), I found this cute apple pattern.
I whipped one up. The neat thing is that there are other fruits and veggies you can crochet for a little cornucopia. I may start working on them so that I might have a complete cornucopia crocheted by Thanksgiving. I think it would make a great centerpiece.
Note: Do not over stuff your apple like I did mine. I think it would look more realistic.
