Beach Towel Bag Tutorial....
Supplies:
- 1 Beach Towel (I bought the cheapest at Walmart)
- 5 yards gros grain ribbon (just to be safe)
- Sewing machine
- Thread to match ribbon
Step #1- Fold the towel in half
Step #2- From the open side, measure in 22" and cut the towel (You are essentially cutting out the center of the towel. The excess that you cut off will make a pocket for the front of the bag)
Step #3- Turn the towel and cut off about 4-5 inches of one side of the towel (otherwise the bag is just TOO big). You may want to serge or zig zag stitch any of the unfinished edges of the towel.
Step #4- Now take the excess piece that you cut out of the center of the towel. This is going to be a pocket. The top of the pocket is going to be one of the edges that is already finished. From that end, measure down 18" and cut the other edge off.
Step #5- Take the pocket and place it on one of the pieces of your bag. You will want all of the finished edges to be at the TOP of the bag. You will want your pocket to be about 5-6 inches down from the top of the bag. You are going to sew ribbon over the sides of the pocket so that none of the unfinished portion will show. Pin the pocket into place.
Step #6- Sew the pocket onto the bag. Do NOT sew the top of the pocket (or you won't be able to put anything in your bag:)
(I had a little excess on the bottom that I had to cut off only because I wanted the pattern to match up)
Step #7- Place right sides of the towels together and pin just the bottom of the bag. 
Step #8- Sew the bottom of the bag... do NOT sew any of the sides or the top. You still want to be able to open it up fully to attach the ribbon.
Step #9- open your bag up and lay it front side up on the floor or on a table.
Step #10- Pin your handles all around your bag. I made the actual handle part of the bag 32". You will want to make sure the ribbon covers the side of your pockets.
Step #11- Sew right on the edge of your gros grain ribbon... sew both sides.
Step #12- Fold the towel right sides together.
Step #13- Sew down the side of your bag (starting at the top) until you are about 6-8 inches from the bottom of the bag.
Step #14- Open up the part you didn't sew and ...
...put that part together.
Step #15- sew the open part together. (I hope these pictures make sense) Do this on both sides of the bag. It just makes a flat bottom to the bag.
Step #16- Flip your bag right side out and you will have an awesome bag to take to the pool!!!
