Choosing fabric is hard!

The next thing I want to make on my list is a cot quilt for L. I know the pattern I'm going to do - just simple squares - but do you think I can figure out what fabric to choose??? NO! Argh! I have been browsing sites for weeks on end now and will think I have made up my mind, but then I change it. *sigh*

I think I need to just buy the next one that I like... surely I'm going to love it whatever fabric I choose???
