craftgrrl | question for you all..x-posted

So, my boy is not a big fan of crochet...he gives me buff for it rather frequently..searches for "crochet addicts anonymous" to help me in my obsession.. Yeah, you can tell we are super serious kids..haha..anyhow.. He is a huge Pacman fan...he even has a pacman tattoo on his arm..

I figure for his 21st that is coming up in July I will crochet him a blanket (he is also a fan of being very warm since he has bad circulation) with a pacman motif..

I kind of know what I want...I am almost thinking it will just be a big pacman screen..ya know, black with the little white dots, a few cherries, pacman, and the bad guys (god, he would kill me for not using the propper terms, hahaha).. But I need to somehow graph a picture so I have somewhere to start..

Does anyone know where I can find a free program online that I can put pictures onto a graph...almost like a cross-stitch pattern of sorts!? I don't know if that makes sense, it makes sense to me.. I just need black graphing lines to go over a picture.. Yeah..hehe.. Sorry, my mind doesn't work sometimes..

Any help is much appreciated.. Thanks everyone!
