I've had a look through the support forums and seen a number of threads that are nearly what I'm after, but not quite. I don't think what I want to do is too difficult, but I just seem to be going round and round in circles trying to figure it out.
I've created a page using the Abundance theme settings and set the layout to 'medium preview image, left & right sidebar', and for the time being I've set this as my main shop page. You can see it here - http://emzo.k-toomarketing.com/
Now What I would like is for the single product pages (which I believe are influenced by a mixture of the Woocommerce template and the Abundance edits) to have the same dual sidebar layout, and the Woocommerce product info that currently appears across the full width of a single product page (e.g. http://emzo.k-toomarketing.com/product/furnishings/union-jack-cushion/) to appear between the two sidebars - rather than above them.
I know I'll probably need to create a new single product page template, which is fine, but I'm struggling to find the code for the dual sidebar settings that needs to be integrated with the Woocommerce product code to achieve what I'm after.
Does anyone know of a simple way to take the template I'm currently using for the main pages and apply it to all the single product pages?
