Pixelated white outline on image after background removed

[jengrant]

Hi, I'm having trouble removing the background completely from an image. It's white and pixelated. I used the background remover tool. I'm on a Macbook Air M2 using Venture 13.3.1. And I'm a beta user for Affinity Photo 2. Please help!!

1. Choose the golf background layer
2. selection from layer
3. feather selection by 2px
4. Shrink selection -1px
5. add mask (to golf cart layer).
6. this will cut off the excess white.
7. for further fine tuning, use the erase brush on the mask with 80% hardness to clean-up remaining white areas.

Thank you... I'm pretty new to this... can you expand on 5 above? I'm not sure how to add a mask. Thanks for replying... yay, I'm learning!

There are several ways to add a Layer Mask. At the bottom of the Layers Panel there’s a Mask Layer icon — click it to add a mask. (Sorry I’m not at my computer to take a screenshot.)

See the To create a mask layer section in the Layer Masks help page for additional details:
