HI PAC -- welcome to our chat room.
This sampler will definitely have a listed of the suggested flosses. Kristi will probably post a list of needed supplies Monday morning. It takes a while to get everything posted because each pattern has to be done individually. The patterns are posted. Then, she starts listing the necessary supplies. She tries to list request as soon as she can.
Define beginner. Have you stitched before or is this your first project.
If it is your first -- it might be a little frustrating. It looks like an easy pattern but there are lots of small stitched areas with lots of space in between. Look for something a like a flower or a cat that only has a few colors and not so much open space.
I don't want to discourage you. I am telling you what I would tell a friend that wanted to learn. Of course, I would give her (or him) one of my personal patterns and some of my own floss. This would be a great second project.
Keep in touch.
