For the last week I have been creating my leggings block for my manufacturing brief as I didn't want to use a trouser pattern. I found this process quite simple following instructions from a Winnie Aldrich book. After I had created that I could move onto patterning and simply traced around the blocks attached the front and back together removing the side seam and drawing 1cm seam allowance and that was my pattern done. I had to use 1cm seam allowance as I am working with stretch fabric so over locking the seams together. If you ever struggle to find a good pattern cutting book I recommend Winnie Aldrich it's simple to follow and has everything in it.
