Adding size variants to featured collection

[flavourbombs]

Hello all, I’ve looked at many different articles about adding size variants/swatches to featured collections and tried some code but to no avail. I’m using refresh theme. Do I need to add something to card-product.liquid? Would love some help! Coding knowledge is slim to none. I only have 3 different sizes for each product and they dont have different images, but they do have different prices. How can I achieve this?

Thank you!

@flavourbombs hey, thanks for posting here.

{% if product.available %}
  
{% endif %}

Where exactly would I paste this code sorry?

I’ve tried pasting it into the product card but nothing happened unfortunately. I need a little more guidance! I’d basically like it to look like this so you can select the size right on the homepage:
