Here are some use-cases you probably didn’t consider when you added support for double-sided designs.
I have some designs that are double-sided, but there are some products for which the two designs don’t work. For example, a double-sided design might be fine for a T-shirt, but I might not want it on a mug or a cap. The only way I’ve figured out to do this is to upload the design twice. This works, but when I go to the Designs page, the same design appears twice.
Here’s another weird one: I have some double-sided designs where the reverse side can be also used single-sided. Again, I can achieve this and it shows up on the Designs page just once. The design there points to where the design is used on the front. Doesn’t it seem like it should include all products that use that design, even if the design shows up on the back?
Perhaps I don’t understand the best way to use the same design for multiple purposes.
While I’m here, I’ll mention that I’d like to be able to apply a product template to double-sided designs as well as single-sided designs. Right now, I have a very limited selection of products, because it’s such a pain to add a new design. For example, with a double-sided design, there are no short-cuts: I have to select every product. Then I have to check every product for sizing and colors. It’s too much work.
