So I've tried my hand at knitting, and I'm not very good at it. Still, I try to do it because it's pretty relaxing. I can do the same knit stitch over and but fail at purls lol.

In saying that, I really want to crochet 3d hot air balloons. I have no idea where to start. Can any of you recommend a site that will teach/show the basics? Someone gave me this pattern but I don't know what the terminology means: http://think-courage-strength.blogspot.ca/2011/09/hot-air-balloon-pattern.html?m=1

I will start small until I get it but then I want to scale the balloons pretty big. do I just use a bigger hook? multiply the stitches?
