The question was about the cross stich in the corner. As you can see in the picture, it is a simple cross stitch. It doesn't have to be pretty, because it will be taken out. The purpose is to secure that corner until it can be sewn down!
My next tip is about using pins to secure the paper to your fabric. I find that if I use small, applique pins where the seams are supposed to be, it helps keep it securely in place until I get it basted.
This is where I keep my hexie supplies. I got the cabinet from a girlfriend's garage sale! What? Doesn't everyone have a sombrero in their sunroom?
The top swings up to give me a place to store threads, needles, and other sewing notions. In the drawers I keep my paper templates, books, and patterns.
Dang! Sorry the picture is sidewises! These are the acrylic templates that you use to easily put your registration marks on your paper templates.
Of course, you can reuse the paper templates, so I had to find a way of organizing them so I could easily find them again. I came up with placing the paper templates with its corresponding acrylic template in individual ziplock bags (the ones that the paper templates come in from Paper Pieces are perfect for this)! If I were truly anal, I would make a label to put on the bag.
Basting hexies makes a lot of little scraps. I made this little thread catcher to hold the fabric scraps and thread scraps. I don't throw the fabric scaps away. I save them and put them into dog beds that our guild makes for our local humane society.
