Just wanted to put my two cents into this thread......but warning, my knowledge is based on, well, nothing. So take it for what it's worth.
I think you should go for the hawaiian print and modern. Do what you like and want. It should be fun and once you give yourself some freedom and "toss the rules!" you'll probably have a great time. And it's not a lifechoice......obviously you're ordering fabric so this is a do it yourself project? If and when you decide it was a mistake, change it. Eclectic is fun, exciting to look at and says so much about you. And remember, it doesn't have to appeal to everyone........it wouldn't even if it was "tasteful" (I use the word and cringe - I despise "tasteful")
Have fun and keep us posted! Hoping to see some crazy Hawaiian prints!
