Hooray My new Nestabilities have arrived

Hooray, 3 out of the 4 new nestabilities sets I ordered have arrived today, can't wait to try them out, I'm still waiting for the Peony one to arrive but I was told they should have them in by end of April so hopefully any day soon, I think out of all my crafting stuff my nesties are my absolute favourite. I have also been very naughty and ordered a couple of sets of Promarkers as so many people seem to rave about them, I couldn't make my mind up between Cpics and Promarkers but thought the only way I can decide is to at least try some out. Any advice would be appreciated if anyone can give me tips on the best way to use them. Thanks Julie x
