Hi Sebastian!!
I think this demo is really helpful for Pinterest!! It definitely covers adding your own captions!
I know Pinterest can be so overwhelming sometimes! I use it to get ideas, but it can also be a bottomless hole, because getting ideas and inspired is great, but physically executing those ideas is an entirely different thing, haha!
I recommend deciding what inspiration needs you have and organize your boards that way. As you can see, I have everything ranging from nail art inspiration to house design + landscaping, etc.
I hope this helps!! Have fun pinning!!
XOXO,
Kate
