There are only a couple of videos featuring Glacier Star on Youtube. There are many from Quiltworx. Too many for me to recommend one over the other. Some things I realized early on. When you get your pattern in, make sure you have all the pages you are supposed to have. Quiltworx will send you anything that is left out. All you have to do is contact them. I had to read the instructions several times to understand them. Her patterns can be done by a sharp beginner. There is a very active FB group and one of the certified instructors is online each weekend. If you have specific questions and can note section, page and item, I am sure someone here can help.
A lot of the papers can be stacked and cut apart at the same time, especially the Templates and the larger pieces of the patterns. They stress in their instructions to make sure you have the same sheets together and they are all oriented the same way before you start cutting. If there are lots of small pieces on a page, then I just cut them one at a time with my rotary cutter. Judy's bag system works and will help with your project. I found that putting her pattern in a 3 ring binder with a sheet cover in each section of the binder worked as well as the gallon bags. I did have to put a binder clip at the top of the sheet cover because everything tended to want to slide out. If you don't have an Add-A Quarter ruler, it would be wise to get one. They work. Judy, sews the same piece of Template to her pattern for all the same sections, in one sewing session. That helps her go a lot faster. For me, I always sew one whole section together to make sure I understand and have the right pieces and colors where they are supposed to be.
And last, but not least.....Scotch tape can be used to put your pattern back together if you manage to have to un-sew too many times. I use a 1.6 stitch length. Any shorter and I saw seams starting to come apart almost immediately especially on the edges of the pattern. Have Fun and show off your fabulous project!
