Hi Van,
firstly congratulations in stepping into the craft fair / farmers' market experience! It's great fun, a great social experience and a wonderful way to get your passion / vision / joy across to your customers. A lot of hard work and tiring, but well worth it! I've had a stall at our local year round farmers' market for almost 5 years now, so these suggestions come purely from what I have experienced with layout.
Try not to have anything on the floor / blocking your table. People will want to get up close and personal with your goodies and leaning over or stepping on buckets and baskets underfoot will deter them from approaching your stand. Also children, dogs, stray chickens can create havoc with those nice floor level displays. Plus, depending on where your craft fair is, some people may be squeamish about buying products for their skin which have been sitting on the ground (in a pretty basket or not).
Adding height to your displays adds texture and interest to your table, so all those tall displays could be turned at a 45 degree angle to make space for the pretty tin basins. Or uses a couple of boxes underneath your cloths to add higher shelf space.
It's great for your stall to look abundant, but beware of overwhelm. What are your most important / popular / favorite products? They should get center stage and be the most accessible to your audience.
How will you offer your samples? Where do you plan to be in relation to your stand? Sitting behind, or standing, or someone out front offering dabs of samples or sniffs of your goodies? People don't tend to approach a stand if the vendors are sitting behind mountains of goods and looking out. It's much easier to approach a stand when someone is already in front of it and looking interested, especially if that person is waving an open jar at them beckoning them in
The small baskets in the back are hiding behind the towers of jars in front, are those your samples? What's in the solitary brown glass bottle? And why does it have a prominent position all to itself? What are the green sticks on the floor?
Labels that are simple and easy to read from a distance are great. Are those business cards in the small box in front? Those are good to have for people who might want to order later, or are interested in wholesale, or are getting married and looking for party favors etc., etc.,
I think it's a great idea to have display jars / boxes and have the real stuff in coolers - we make chocolate too and that's how we have to work, people don't mind at all, just make sure the coolers aren't so cold that you'll have issues with condensation when you take things out.
Your colors look good, natural and neutral. Where will your banner be?
Good luck with it! It's a really fun way to meet customers, get feedback and learn a whole lot about why you are doing this and what it really means to you. Have fun with it! Oh and make friends with the stall holders around you, oftentimes they can be your biggest customers and promotors. Be generous with samples to your fellow vendors please: what comes around goes around
