Trimming for Applique

I have one favorite tip that I use for creating cleaner edges when doing machine applique in the hoop. I use a lint brush. Not one of the ones with adhesive, one that has velvet with a nap on it.

After I attach and trim, I brush in all directions.

Here's what a piece looks like after trimming and before the lint brush.

And here's what it looks like after I go over it with the lint brush. 

I can easily trim those threads now that I can see them.

I keep brushing and trimming until there are no more threads that stick out to be trimmed off. Even then, I'll still have the occasional thread that pokes out where I don't want it. For those, I suggest a permanent marker.
