I finally worked out how to create coloured image brushes for both Vector & Raster formats in Designer.The raster brush instructions also apply to Photo too.
When a member of a Face Book group I belong to, asked how to create a brush from a png image, I set about creating a video. No text or voice-over, just some nice relaxing Royalty Free music and my mouse movements.
Recorded on a Windows 10 Pro system but hopefully Mac users will be able to see what actions need to be performed on their O/S.
I have also included the two single brushes here with Permission from Nikki.
Any comments are welcomed.
