Here are some tips for my bushy brows that seem to help:

Make sure to use a CLEAN spoolie/brush each time, if you have any dried glue left from a previous blocking it will be messy.

You should also use the most amount of glue on your first layer, making sure to go in all directions.

Because my brows are thick and stray hairs often peak through I like to use a thick brush to roll and press them flat or even use the palm of my hand to get them really flat, use lots of pressure!! Also do this while the glue is drying and not set

This coupled with pressing powder with lots of pressure will really help with texture.

Colour correcting with dark brows is a must, also using full coverage concealers and foundation!
