Tricks of the trade? Having great resources for kit materials. Yes, creating your own is and always will be most awesome, but to have that action/ribbon/style already for you to use? priceless. definitely worth the small amount you will pay for them! If you can find great quality CU Freebies even better. These are the sites i HIGHLY recommend if you're looking for designer resources:
Http://www.actionfx.com Memberships are quite inexpensive and the amount of information is just INCREDIBLE!
http://www.atomiccupcake.com again, the quality and number of actions/styles and yes, even kits if you're a scrapper is fantastic!
http://www.obsidiandawn.com Love, Love, LOVE her brushes! She gives them away for free!! Do her some lip service, and donate too if you have the means!
IF you're a PSP user, an invaluable resource is http://www.outlawbydesign.com her tubes are just fantastic!
