Questions for designers (again)

Hi designers, sorry to bother you again. I will probably explain what I'm trying to achieve badly, but please bare with me:

Glitters / Sparkles

  • Is it possible to make a pattern glittery? So it's as if the pattern has been embroidered on with sequins?
  • Same question, but for decor?
  • Or Edging?

Two Tone Taffeta

I've attached a couple of pictures to show what I mean. I think it's probably as simple as changing the colours of the glare and shadows. However, when I change the colour the shadow layer it loses all shading throughout the whole section I'm working on.

Perhaps I could do it with a brush layer. Am I able to turn off the shadow layer for when I save it though?

If you've a much much better idea on how I can create the effect please please tell me :) xxx

Thank you in advance.
