I do my best to get all the cutting instructions before I go on any retreat. I cut better at home than with others. I know I am too easily distracted.
I list the supplies I need and make sure they are all labeled. I have a clear large cosmetic bag with zippered pockets that I put my rotary cutters, scissors, needles, extra other items, including the throat plate with the wider opening and tools. Luckily there are 3 metallic mesh bags in this case, so it holds more than it looks like.
I take my camera and a spiral notebook for note taking and recording the names and contact info of those people I want to keep in contact with or who are great resources.
I'd love to have 2 sets of everything I'd need but don't feel I go to enough retreats to justify the cost and the storage of it all.
The Tutto carrier is wonderful as it holds a lot of stuff.
