flexible ruler to help you get the curve you want. Now draw four straight lines across the pattern. 1 1/2" from the bottom and 1 1/4" apart. These are your ruffle guides. This is the only pattern piece you need for this purse. Everything else is just rectangles.
Get the fabric for the outside of the purse ready by laying the selvage edge so it faces you right side of the fabric down. Now bring the opposite cut edge to the selvage edge folding the fabric in half. Lay your pattern piece so the little straight sections of the curved top edge are directly on the fold. Make sure you have the left side as close to the cut edge as you can get it because you will use all but an inch or so of this fabric.
Now cut the lining out the same way you cut out the outside.
And you're done. Have fun and if you make one be sure to leave me a link to a picture in the comments section. I'd love to see it. :)
