hi
try making a decision on the size of your purse,and how big the bottom part of your purse is to be
cut outer fabric and lining to match. (quilt at this time).baste around edge
fold up bottom,CREASE...fold over top CREASE (looking at what size your purse is to be)
your turn over has determined the bottom part of your purse ...
sandwich zipper between 2 pieces of fabric on either side of your zipper
(you will have fabric..,zipper..fabric )fold over and press.
Trim this to the size of the lower part of your purse now
sandwich between the lower fold of your purse
..PRESS well..cut bias and go round your purse
finish with a button or stud
so your bag whe open will have an open section ,zippered section and an open section
hope this make sense to you be feel free to ask any further questions if you want to try this Cheers
