Collection with specific variants

[NelsonWoodworks]

I have a woodworking website that is selling wood for people to make pens, cutting boards, bowls, etc. In my products I have the different species of wood. For example, Walnut. I have each size listed as an individual variant, 3/4” x 3/4” x 6”, 1.5” x 1.5” x 18”, etc etc. Some species have 10 variants, some have less. Overall I have 60 or so different species. I want a way to take specific variants from specific species and create a collection from that. How can I do this??

I assume it involves creating custom code to make it work? I had done that, but it’s a pain to add the variants, would love to have a decent UI to do it. Even if I need to download an app, but can’t justify paying an extreme amount each month

1. In Shopify, collections are based on products, not variants.
2 . If only a few variants from each product matter, you can create new products for those specific variants and add them to a manual collection.
For example, create a product like:
Walnut Block – 1.5” x 1.5” x 18”
Cherry Block – 3/4” x 3/4” x 6”
3. Then include these specific items in a manual collection like "Best Sellers".
