First of all, I like this app. It’s a great idea and when the author writes the directions, you can actually follow.
That said, most of the instruction seems to be canned and the author didn’t rewrite it in ‘human-speak’ like he did with the t-Shirt. As a general rule (for me anyways) If there’s a photo of the thing you’re supposed to make, the author wrote the instructions, and you shouldn’t have trouble completing the item. But if you see a line drawing in the gallery, you can pretty much forget about it.
In short: Good App. Worth the buck. (Oh! And when you’re scrolling through the list of things to make, click INFO to see the directions.)
