Crochet pillow

Those of you who have been readers of my blog for a while now might remember the large crochet circles i made before. Never got around to actually doing something with them. I sat down, picked my favorite and turned it into a pillow! Do you like? I do. I will keep this one for myself, but maybe will make some in the future to sell if people like them. I'm just wondering since i didn't turn it into a cushion cover, could i wash it? Could i throw it in the machine and have it come out in decent shape? The fabric used for the pillow and the crochet top have been pre-washed, but what about the fiberfill? Not sure. And scared to try in case it would ruin it. Keep it fresh with frebreze? ;) It's more decorative anyway, so i doubt i will actually have to wash it a lot. But if i would make them for sale they should be able to be washed right?
