Are your fabrics all organized by color, type, amount? Sometimes just putting them together, or moving one color/print next to another and playing with them, while looking through patterns helps.
I have a couple patterns or ideas of things I want to make and have started to collect fabrics so I have enough for that project.
I search the internet, magazines, books and such until I find something that just HITS me. It takes time sometimes.
Do you have a color in mind for the one you want to curl up with? A print perhaps?
Good luck. It will come to you.
