oh, we have something in common. I also make banners. not quite the same style, but both fun. you have a ton more sales than I do and I've been open longer. so I feel a little weird doing a critique on you. please don't do one on me, I'm not prepared. my shop needs more work.
so, let me do a short critique.
like your shop banner, don't love it though. I would love to see one of your items on the shop banner, it would match better.
have an avatar with one of your items.
I think your banners should have a category of their own. then alphabetize the category names.
do you know how to rearrange your shop? it would look nice if you had all the same themed items together.
use all five picture slots.
http://www.etsy.com/listing/88230583/safari-birthday-banneruse all tags. this item could have the tags: birthday banner, party banner, wall decoration, safari banner, kids party, toddler birthday, birthday party, zebra banner, giraffe party, etc. anything and everything the customer would search for to get an item like this.
offer international shipping. go to usps website find out average cost and list them.
I guess it wasn't a short critique, but those are the opinions of a shop with less sales than you.
