Good evening. I've just got going building my shop in the last week. I've uploaded a few designs a day and am enjoying the process so far. I'm starting to get a little bit worried though with the quality of the images I've produced. They're fine for the listings but reading through here, the versions I have uploaded to PrintShrimp will likely not be high enough quality for printing when I actually get an order. I have been creating an image in Midjourney, upscaling there, then editing in Canva. I've been reading through a few threads and it now looks like I have missed steps of further upscaling and exporting my png at a specific size/res from Canva. I'm not particularly technical or au fait with these tools previously. Is there a how-to video? Or a guide for idiots on what steps/tools I should be following? And what pixels etc for A1-A5? I know you have to speculate to accumulate but do I really need a Midjourney subscription, an Upscayler subscription and a Canva subscription to create a high enough quality image?
