I need a new look for my Etsy shop's banner. I need to be able to use this banner on Facebook as well (I have a Facebook page linked to my Etsy shop). Banner needs to be sized right for Etsy and Facebook and editable as well for when I need to do minor changes (e.g., add text for promo codes). Link to my Etsy shop and Facebook page will be provided to the winning bidder. Thank you.
