I never understood the big deal about a retreat. I have a sewing room all set up and I can sew anytime I feel like it. Well, I went to my first retreat last fall and it was so much fun! Sewing with other people and making new friends is great.
My friend just whipped through her projects and got so much done. She had precut all of her fabric. She already has her things cut out for our next retreat in June. I hope to get my projects cut out ahead of time too.
You might want to have a small table right beside you so that you can have your own cutting mat and iron/pressing mat right next to you. It seems everything has already been mentioned that you will need.
Have fun!
