I use canva to create my posters and it only supports 4k x 7k px, should i just get PhotoShop instead because the posters will come out like 150 dpi at A0 and look blurry. Or is there another way?

I am searching for some free mockups but don't know where to look, i suppose many buy mockups off etsy or an app but i am just getting started and want to get a hang of it first. Thanks!

I’ve created images in midjourney and upscale creatively before downloading them, when I preview the image it says it has 72DPI which I don’t believe is enough for printing although Tom has said in his videos that if you upscale creatively it will be good enough quality for resizing to any size. Do I need to do anything else to the image or is it actually ok for resizing and printing as it is?

Hi, i just listed my first posters in the "My products" section on Print Shrimp, should i list A-sizes first and wait till i get a sale in another size then list, or do i have to edit my posters for all the sizes before putting them on Etsy.

Hi! i am very new to POD and i am trying to figure out how to make a good ai pic of everest. Is midjourney good enough upon request or should i ask it to copy a picture of everest, and in that case i suppose the pic can't be copyrighted?
