When is big big enough?

I am having a serious mental block about finishing my crochet scrap-eating afghan.  I keep thinking "the next row will be it" and sure enough, it still seems too small.  Now I can't decide if it's actually too small or if I just don't want to stop working on it.

I did a few of my common afghan-sizing tests to see if I'm getting close to having it the right size.  It's missing a few patches that haven't been attached yet (or made yet for that matter) but I think we're getting close.  But I thought I'd share my highly scientific test methods to determine if an afghan is big enough or not with you.

Test #1.  Do you get cold feet during naps?

This test was repeated several times for the most effective results.  If this test is passed, move on to test #2.

Test #2.  Does it make an appropriately sized fort?

Yes.  Move on to test #3.

Test #3.  Can you reenact scenes from "Titanic" using the afghan as a door and a cat as Kate Winslet?

Affirmative.  Move on to test #4.

Test #4.  Is afghan big enough for more than one cat? 

Clearly, it's not.  I think I'll add another row of circles. 

If you find yourself wanting to do these tests and lacking a cat, you're welcome to my old yellow cat.  She hates life and pees on the floor sometimes, but she's a trained yarn snob and will deliver highly accurate results.
