First step *make sure they say ftu offsite*
First of all, we need to think about what "aesthetic" we want our bio to be! For this example, I will be doing "space" as the aesthetic.
After you chose your aesthetic you need to go onto Deviant art and search up FTU -insert aesthetic- dividers/icons/pixels or whatever you are looking for. If you can find what youre looking for, try to switch up your words a bit. Once you find something similar to what you want, you should save it to your favorites. While still on the image, I like to scroll down to "more like this" and go from there, finding more icons that are what i am looking for. You should repeat this until you have a decent amount saved so you can piece together what will actually go together.
Example: (im on mobile so it looks dumb but basically you should just have a bunch of icons/dividers favorited)
Second Step
Once you have all of them favorited, decide what one you want to use first and then save it to your device. Then you want to go to Gifyu, ypload the image/gif, then copy the image url link. Go back onto wolfplay and press insert and then press image. I dont recommend resizing it because they are already pretty much the size you want them. If you need a visual on how to do this step feel free to comment and I will reply with how to do it. So if youve done it correctly, the image should now be in your textbox. Like this:
Third Step
Basically this part is up to you. Whatever text or anything else you want to put into your pack bio is up to you! For the example, I will be doing something similar to my bio but more related to this aesthetic.
So i have my solar system divider at the top of my bio. I will then hit return on my keyboard and jump down to the next line. I then will go onto my blank space copy website and copy that blank space text. I will go back onto wolfplay and paste it underneath the solar system gif to create space in my bio. You can do this however many times you want to make the empty space bigger or smaller. I then will hit return again and start typing. I then will repeat step 2 and find another image or images in my favorites that compliments my first divider and place it in my bio. DONT FORGET TO SAVE IT! I recommend saving it everytime i put in a new feature so I can 1, look at how it looks and make changes if needed and 2, so I dont get logged out and have to start all over or something. It should look something like this;

Hi my name is Space and I love wolfplay!
Pink is my favorite color!
Let's be friends!
----
It should look something like that! Just dont forget to use the blank spaces and such so it looks more spaced out and not all clogged up.
Fourth Step and final
Credit your images! I always go to the "profile" part and credit everything there. I also make sure I do mine in direct order of how I placed everything just in case I need to make changes, i find it easier if they are in order.
Here are the links for everything Ive used here;
