I've been working non-stop on this since Wednesday of last week. XD
I started off by using some foam from a Walmart bed-comforter to cut out a Lucario head-pattern using a Styrofoam wig-manikin-head as a base. I then duct-taped the foam together into shape, and then used some fleece fabric and the leftovers of the hoodie I used to make my Lucario "top" for the covering. It has eye-holes covered with a sheer-black material, and two little air-holes cut out in the top and bottom of the partially hollow foam snout. I kept part of the original sleeves of the sweater for now, in case they become beneficial for keeping the neck-fabric in place when I wear it with the rest of my Lucario costume. It still needs a few more little touches here and there, but for the most part it's pretty much complete.
And this, like ALL my other cosplays, was made for dirt-cheep. XD
