I find it harder to complete someone else's work than to start from scratch and make my own. Since you have tons of fabric, I would choose a simple project from the videos at Missouri Star Quilt Co. Jenny has some nice beginning projects to get you started with a project of our own.
Once you have completed a couple of your own projects, go back and take a look at the partially completed ones and see if you want to attempt one. Congratulations on your new acquisitions!
