Let's also keep in mind that we aren't talking about a massive section of a supermarket isle full of the same product, each one trying to get noticed. That is not what most people here do and certainly not what you are trying to do - you're having a stand at a church fair, so I'm pretty certain that you have much more leeway than you think.
I go back to my original point - use something that will appeal to the target market (which comes from my marketing background rather than your psychology one). If you want pure and natural and so on, a lamb is fine.......if most people who you are targeting associate a lamb with pure and natural. In particular, the image of a lamb that you choose (not all lamb pictures will mean the same).
If they don't, then you need to look at something that does give the ideas over to your target market.
Also, the LSS font has to change - and first I thought that it was dollar signs!
