craftgrrl | Sewing wrap skirts? (Reply)

I've just started sewing after being given a new sewing machine as a gift last year. Prior to that I haven't really sewn anything since grade 9 which is... eep, nearly 16 years ago!

Anyway, I've successfully made a few simple skirts and altered a few things. Now I've found some fantastic fabric that I want to make a wrap skirt out of but I need a little advice.

The fabric has a Halloween print with a border and I think it's supposed to be used as a wall hanging or a cushion panel. Sort of like this except Halloweeny: http://www.jbquiltingfabrics.co.uk/shop/index.php?main_page=popup_image&pID=523

I think it will make an awesome skirt but I'm wondering how to do it. I recently bought the Sew What! Skirts book and it seems like the best way to get a wrap skirt to sit right and fit properly is to cut the fabric as you would for an a-line skirt.
The problem with that is that the fabric I'm using has a border on it so I can really only use it in rectangular panels.
Would it look odd to add some black fabric at the edge of each panel to make the a-line shape? Or should I make the skirt from black fabric and just have the front panel of the skirt in the Halloween fabric? Is there a better way to make a wrap skirt from rectangular panels?

Thanks in advance for any help or suggestions!
