Now finding 25 inch zippers is a pain. So I have found duvet cover zippers are 60 inches long, so you can get four sunglasses case's with the one zipper; BUT you only have one zipper head, so I buy three cheap zippers (usually 3 for $1) and use the zipper heads from them.
The one I used for this one was a 22 inch zipper and it was a pain to put in.
Then I made her a Sling Along Bag and it turned out lovely. Also a lot easier to make the second time around.
Fabric I used was:
Grey Poppy was Sarah Watts Magic Forest for Cotton + Steel (I would not use this fabric for bags in the future, not enough body in it; too soft for a bag)
Coral was Rae Ritchie for Dear Stella #SRR512
Grey was Basic Grey Metropolis for Moda Fabrics #30565
Below is one of the ladies bag who took the class with me, in a gorgeous Tula Pink print. She hadn't quite finished it when I took the photo.
Here are my two beside her bag. Such a lovely selection of fabric there.
