Welcome to both Tom and Mulberry to the Oil Pastel Channel. We are glad you joined us in trying your hand at OP.
Pat has givent you some suggestions and a link. For members new to the OP Channel we ask that you read through the thread accessed by clicking on "Newbie" in my signature line. (There are other helpful links in my siggie line as well). Doing so will take you to a thread that provides answers to the most common questions about how the Channel is organized into various forums, what each forum is for and guidlines on where to post what and giving and getting critiques.
It also contains links to ALL the OP forums and subforums, links to threads giving basics on tools and brands of OP and other general questions.
We want to be as much help as possible and provide you with information you need; posting questions in the OP Talk forum will most likely get you more responses. If you browse the OP Talk forum for the past month there have been a number of threads that have extensive discussion of the topics you are interested in.
If you have trouble finding the info, please don't hesitate to start a thread in OP Talk and ask your questions. This is a GREAT bunch of people and just about everyone acts as a Guide whether they are called that or not. Everyone wants to help and support your goals.
Thanks again for coming in and hope to see you around the forum.
