Taking out a target


Experienced Member
Hi everyone! :)

So, I've discovered recently, how easy it can be to teach a trick by using a target (sends and doing tricks without looking at me...).
But the problem that appeared to me:
How can I take out a target?
I've tried quite a couple of things, but they just didn't work.
1. Just suddenly took it out, and just asked for the trick -> Pami got completely lost...
2. Getting smaller and smaller targets-> she just starts looking for the original,or she just can't see it, if it's too small.

The other problem: Even if I do these "target-using tricks" at a lot of places, she just does them at some fix points. I can't really explain this better... :S

any ideas, tips, advices are welcome! :)
Thanks in advance! :)
