Every artwork at Redbubble is selected for how well it translates for a given product. This may be because of the size of the artwork, but also because the design may not always lend itself well for a particular purpose.
It may be that in the short term more revenue could be generated by offering artworks in a larger range of products, but the buyer will not be well served by this approach.
Visitors to Art Lover VIP's Redbubble store will find that some artworks are only available on a limited range of products.
The aim of Art Lover VIP is that everything made available at Redbubble is beautiful for person and home.
