I Have 4 Fat Quarters
and I made a lunch bag
I used the tutorial from Pink Penguin. You can find it here. There are some things I wish I would have done different. I used Decovil Light on the outer. I should have used SF 101 and Insul-fleece. I did sew some Insul-fleece into the bottom, but...
I also made some poor design choices, but meh, I used 4 of my fat quarters. I made this in a day. I could have been faster, but I have a cold and I am way slowed down.
