I am going to do a show this weekend and am a little nervous. I love both their bases, but wondering if anyone has had any problems with them? I'm just worried since I've had the bases about 7 months, and they are still good to me, but am wondering if I'm pushing it since the shelf life is usually 1 year. Also, I am using the oil soluble colors from MMS, and I'm making the labels now...they have them with 2 different things. EX. CI 77499 (black Iron Oxide) & Castor oil. Do I use both or can I use just one??? I called but all tech support is gone!! I wanted to make the labels today. Have alot more to get ready. TIA Deronda
