I also brush powdered sugar anywhere I've used edible marker and that helps with smearing.
Thank you for your service and advice! When I shipped the large boxes, each layer was sandwiched between Saran Wrap. Bubble wrap between saran.
I bought a food saver for the deployment and overseas boxes.
I have changed the baking process to only baking what I can get done. I do make dough in volume and roll out. Always have some ready to go for last minute requests.
i like the powdered sugar tip too! I can't pipe the fine lines on the aircraft cookies. They are a lot of work and I worry about smudging. I'll try your tip.
