For awhile now I've had this project bookmarked and on my "to do" list. Since we're heading to a birthday party this weekend I thought it would be worth a shot to make and take it as a present. The verdict? It was easy to make but the instructions definitely need some tweaking. I am a visual learner so more pictures would've been helpful as well. Due to the fact that I had some difficulties making sense of some of the instructions it took me a bit longer (due to having to unstitch/restitch, etc.) to make. It is a simple project but if you are a beginner sewer you definitely need more clarification on the how-tos. I think it's a cute little gift so I am seriously considering rewriting the tutorial for my own sake. I'll let you know when/if that happens.
Here's how it turned out. You may or may not (depending on how much of a perfectionist you are!) be able to see some cosmetic blemishes. *Sigh* Live and learn!
Instead of going with the traditional race track or Disney "Cars" theme I opted for the "Woodie" look since we are back in the islands. It's got the total surfer appeal! The pocket holds three cars. At the time I thought using a constrast fabric for the pocket was a good idea. I think I should've stuck with the same red woodie fabric instead. Again, live and learn.
A couple of cosmetic issues - fraying of the ribbon for one. The instructions recommended using grosgrain ribbon - of course I couldn't find any yellow so I settled for yellow twill. Next time I will try something completely different - just not sure what yet. 
I actually managed to find a "Woodie" car to include with the bag! :)
Regardless of the headaches I encountered I think it turned out pretty cute. I'm looking forward to making another one. Next time I will probably include some velcro to keep the bag shut when not in use.
On that same note - have you seen THIS one?
