Having way to much fun with these!
I used Melon Mambo and did a faux crocodile skin technique.
To get the crocodile skin look I took my versa mark ink pad and pressed it everywhere I wanted the effect to be. I then used crystal clear embossing powder covering all of the versa mark ink. I then took a toothpick or you can use anything with a dull point like a stylus and made my lines. Make sure to wipe off all excess of ink and embossing powder off of you tool before starting a new line. After making all of the lines use your heat tool to set clear embossing powder. I used 3/4" circle punch for all four bottom corners. I suggest forming your conners first before inking and embossing. You can't see it from this picture but I also have 4 black brads on the bottom of this purse. I love this effect!
The other purse I used Timeless Portrait DSP and black card stock. I made a second purse with the black CS and then just cut out the pieces I wanted to use. I added the stitching with a white gel pen. I used basic black ribbon taffeta over a piece of black CS for the handle and secured with to 2 vintage brads and an Antique brad for the front.
Idea is from Lynda's quiet time blog.
