Displaying a blog article based on variant selected


I’m hoping to get some help with my product pages, basically I’ve product options set up as different feature fabrics for bags I make (www.mattt.com.au/matttpack)

I’m trying to work out a way to change the fabric description field based on the fabric selected.

At the moment I’m using an app to do this, which works though uses the product.description field to just show the relevant content. This is a pain to keep updated and messes up listing products on Instagram etc as the product.description is far too long.

I use blog articles to populate other parts of the website and it works well, basically many products use the same fabric descriptions, so having only one source for them will make my life easier :)

I’m also using a custom version of the Atlantic theme.

Any help most appreciated :)
