Detachable side pockets for pack?

I am hoping that a few of you can help me out.

I’m looking for a detachable side pocket that will fit a water bottle, preferable a 48 ounce soft sided canteen type. My hope is to use this pocket on my Osprey Talon 33 pack for weekend trips. I’ve seen a few patters for products in the MYOG section of this site but unfortunately I do not have access to a sewing machine.

Thanks for your help!
