The guest speaker was Margie. She is from LaGrange Texas and owns a Quilt Retreat in LaGrange. You can find it here. I bet her facilities are fabulous if they're anything like her quilts. She spoke on Medallion Quilts and more specifically Round Robin Quilts. I can't say enough great things about her work. They are so stunning. She gave so many tips and tricks about participating in Round Robins.
The first tip is to put all your fabrics in a small carry on type suitcase with rolling wheels and a nice pull out handle and also a nice garment bag to put the quilt in as it grows. It keeps it protected when passing from one person to the next. If you'd like to make a matching garment bag for your quilt, you can find a tutorial I shared here.
She says you should never start with anything less than a 14" center. 12" is too small (particularly if you're wanting a bed size quilt.
Be specific about what you want. If you want leaves, and gourds, and pumpkins, say so.
Put at least 8 yards of a variety of fabrics in the suitcase. They most likely won't need it all but it gives them plenty.
Needless to say, most of her centers on her Medallion Quilts/Round Robins are needle turn applique. They are awesome in themselves.
If you only want an accent of a certain fabric or color, tell them that and then only include a yard or less than that. That way they won't have any choice but to only accent with it.
If you have a specific pattern for applique, piecing, embroidery, or whatever, include it. It doesn't mean it will get used but it probably will by someone.
She recommends no more than 4-6 people in a round robin group and suggests that 6-8 weeks per row is best for a timeline between rounds. She says to plan the order of who will receive it, spreading the specific talents of the participants out. For example, don't pass it to two applique-er's in a row. Split them up.
She even has a small booklet you can print and put with the Round Robin project. She has so many more tips that I can't remember. If you get the chance to hear her speak, you should go. I learned so much!!!!
