The patterns for the Side Borders will post October 1 and the patterns for the Top/Bottom borders will post November 1.
I am working on both of those right now, writing detailed blogs with the methods I used.
Becky uses freezer paper run through an ink jet printer. I use either Quilters' Select Print and Piece Fuse Lite or C&T Wash-Away Applique sheets. If you want to see the process I used on Ruffled Roses, I have detailed instructions here:

and here:

For now, if you want to practice machine applique', I suggest you draw or find a simple applique' design and work on your technique now. Come October, you will be ready to go when the patterns are released.
