i am busy with quilting from a book that called 1000 quilt patterns, what i do i increase the pattern and copy it to A4, then i copy this page to nother 30 pages, i pin it to the quilt...and quilt. only this way i stay near or exactly on the line.you get in this book different segments of quilt patterns - colomes, area, squares etc. - so you can choose what suits to your quilt.
good luck!!
