I'm sorry I don't have a pattern to share for this project.  I just sort of "winged it" and came up with my own design for this busy bag, and in the process, busted a couple of fat quarters from my stash. Inspired by one that quilty friend Jacqui received as a gift recently (which I secretly coveted) I decided to try my hand at making one for myself to jam in among my books for quiet moments while I wait between lectures.

Closed, the busy bag measures about 6" x 9" and a strap holds it closed with Velcro tape.

I zig-zagged a rectangle of felt to the pocket on the inside front cover.

I stitched six ziplock bags to the centre, covering the bottoms with a strip of the contrasting fabric. 

On the inside back cover, I zig-zagged a larger piece of felt to "stick" small fabric pieces to while I work.  I also stitched small pockets to hold a stitch ripper and glue stick (I'm a big fan of freezer paper/glue stick applique.

I actually made TWO of these, because I've got my 50,000 hits mark in mind, and decided this might be a welcome gift to someone in celebration.  I'll post more details about that as we get closer.
