If you make it the pattern size you can fit a small child in that junk' around purse. LOL
I have made so many I use 1 1/2 for outside and 1 1/2 for lining. I cut 5 inches each from the outside fabric and the lining for the handles. Do not skip putting batting in the handles, that makes a big difference. You can use a thick braided rope for beach and utility use and skip the handle making.
I lay the two fabrics RST and sew around leaving an opening then trim, no measuring needed. I can can make one in less then an hour from cutting to finish. I highly recommend the Clover Love to Sew bodkin for the elastic. I put in the elastic and sew one end down before it goes past the opening. Then pull the bodkin through gathering as I go and sew the other end at the opposite opening while the bodkin is still holding it. The bodkin has never released no matter how much I pulled on it and my hand does not get tired. I pulled fabric to make two more bags this morning.
