I have one with baggies that I've been using constantly for at least 15 years (really???) The baggies are the sturdy kind & are stitched to fabric that is attached into the bag by velcro. This makes them easy to take out if you want to use them for floss (I have never removed mine :-) ) It was purchased at a craft fair, sorry no pattern but one of the links shows a similar one, only mine is square.
