Funny StickersAnother feature of PicsArt is its cutout feature, which lets you create stickers that are shaped like portraits or objects. For example, you can create square or heart-shaped stickers using this feature. To do this, open your picture and tap the Tools option. From there, tap Shape Crop, and select the shape you want to make your sticker. You can also change the border width and apply different colors. Once you're done, tap the "Save" button and save your sticker under Sticker - My sticker.
