Just finished this...only took me about 3 weeks cause I got bored with it before I sewed the ends on...it's for my niece
OK, so I've never posted a tutorial, if you have any questions, lemme know... here goes...
1. Decide how big you want your bag to be…I cut my ends 20” around. (I made a paper temp. so that I could trace it.)
Round Pieces to cut:
2 interfacing
2 lining
2 outer material
* Lining was pink, I also used pink as the outer ends* 
2.Decide how wide you want the “body” (for lack of better term), and cut 1 each of interfacing, outer, and lining. *The length should be the circumfrence of the circle + seam allowance*
Sandwich Lining, interfacing, and outer material, and sew all pieces together, right sides out, so that it can be worked with like it’s one piece.

3. For the straps:
*I think it would be easier to buy some of that nylon strappy stuff, which if I hadn’t been in such a hurry, I would have and the next time I make one of these, I’m gonna do*Decide how long and wide you want them to be, (I cut them 4” wide, and 44” long) and cut 2. Fold them in ½ longways, then fold the the edges to the middle (like bias tape). Then sew the ends together so that you have one piece.

4.Pin straps flat and stich.
*Make sure that you pin the straps on evenly*Sew in zipper (look for zipper tutorial for help)

5. For the ends:
Sandwich and sew the round pieces the same way as the ‘body’. Pin to the edges, right sides together and sew.
**When you sew the last end on, make sure you leave the zipper open enough to turn the bag out**
Voila!! You’re done!!
