I saw one of the donators had a profile picture of a BanG Dream! Card template with a custom image on the inside. I searched the internet and couldn't find any templates of the frame, (I didn't search massively because who has time for that you know,) so I decided to take time to make some and share them with you. An example above is Bongo Cat in a 3 star, Hello Happy World, Cool Frame. At the moment I had only made Hello Happy World 3 Star frames of all different types, and more to come!
If you do download these templates, there are a few things you need to know
They are transparent so no need to wipe out any white parts
You will need a photo editing software. I created the templates with paint.net, but you can use photoshop or any other software of your choice
Make a layer underneath the image, I thought it would be obvious, but just some help if you do or did get stuck
You will have to erase the corners if your image exceeds the frame, so that way you can have a clean smooth frame like a real BanG Dream! Card!
EDIT: Pastel Palettes and Roselia frames have been added!
EDIT: These are pre-made so you will be able to put a photo behind it. Ones found in Gallery don't include the band logo or their skill type, so this is more of a take it and use it kind of thing, not a DIY, you have the easy part to do :D
