I don’t need it as elaborate, only apparel. Are there any apps which would give me a product page similar to teefury.com where I can have one product page for each design, containing options for all product styles (tee, tank, sweatshirt, hoodie, etc..), ?
Hi @cam94z28 
I have not seen an app that does this specific thing. It looks like a helpful feature for apparel with that config (same print in multiple variations of clothing).
We have done a similar theme customisation recently and we used metafields to tie the products together and make them accessible via the single product page.
