OP, can you either take the raffle pic off completely, or can you make a table with no borders in whatever you're using to design the webpage, so you can control how far across the page it goes? The distortion really doesn't do your web page any favours. It's also far too big, I think, and distracts from your overall design.
On your products page, it doesn't look great that the pictures aren't all the same size - nor why personalisation appears to have been put in half way down, there doesn't seem to be any ordering (alphabetically, by price). I would expect to see this separated from the items to buy.
I wouldn't have confidence to buy from a site that looked like this, can you emphasise whoever it is who is providing your backend buying service? I'm sure it's perfectly legit but it doesn't look like a site you could trust with your credit card details. One of my fave yarn shops has a pretty workman-like website but has a privacy policy which is reassuring.
I would agree though that it's a nice clean design (raffle problem aside) - another thing that's nice on craft sites is an accompanying blog - I like this one on another of my yarn sites.
Good luck with the site!
