@Apple_Pigs u search for what you are currently interested in (fandoms, cooking, clothes/outfits, wallpapers, drawings and drawing ideas/tips, etc) and after scrolling through some
If you find a pin you like
you save it!
And since you can find almost anything there you can make sections to organize your pins.
The more pins you save the more Pinterest will recommend similar pins and pins it thinks you would be interested in :>
(Like if you saved stuff about cats, you could get other animals and possibly fluffy things)
