shadow of doubt

I started working on one of the washcloths that I hope to make for my cousin's gift. She's going to be moving out of her parents' house in January and I want her to have something different. So, I'm making her 4 flower shaped washcloths, the ones that are featured in the new Interweave. I'm done with the petals, and just joined the five this morning. But, I'm watching the yarn ball get smaller and smaller...to the point where I doubt that there will be enough to finish. I've got my fingers crossed, 'cos at this point in the game I don't want to have to order more yarn. I'm also going to make some cute soaps to go with it. So, this a gift idea that I don't want to ditch.
