Playing with Half-Square Triangles

I am working on a new baby blanket. I love the fabrics, all bright colors and Eric Carle prints from the Very Hungry Caterpillar.  The half square triangles that are the basis of the quilt are fun to play with.  I ended up spending a good 45 minutes flipping them this way and that to see the different patterns formed by the white and the bright colors.  All the different patterns were made by simply rotating easy square where it lay.  None of the blocks have been switched or moved to a different spot.  It is amazing how different each variation looks.

My Original plan:

How about zig zags? I think Marshmallow approves.  Oh, if I haven't mentioned it before we adopted a pair of half grown street cat kittens. Meet Marshmallow, he is "helping" me this morning.

Stripes?  This one turned out to be my least favorite. 

Squares?  I think I am leaning toward this one right now.  Marshmallow approves.  David suggested this one last night and I didn't like it then, so if I choose this one I will hear about it. Sigh. 

The other kitten Orerow  jumped in to help Marshmallow check out the quilt pattern. After their "help" a few square may have been moved around. (About his name, there was a mix up the the vet papers and Oreo became Orerow.  Sounds like Scooby Doo trying to say Oreo.)

I like this pinwheel/hourglass pattern but I had such a hard time trying to lay it out that I think I will wait until I have a little more experience before trying this one.  In this pic you can see the coordinating fabrics.  The Hungry Caterpillar is the backing and the green numbers will be the edging. 

This is the last variation I tried.  I tried it two ways, one with a  white center and one with a dark center.  For some reason I like the dark center better. 

I can't seem to make up my mind which I like the best.  I may have to buy some more fabric and make more quilts just so I can try them all out.  Darn.
