My favorite trick is this special sewing machine presser foot:
The Curve Master foot fits most sewing machines. I use it on my Juki 2010, and also on my Viking.
Aside from careful cutting, the most important trick to stitching curved pieces together is understanding the "give" of fabric. Many curved piecing instructions insist on lots of pins -- I use only one, to mark the center of both pieces.
Pin once in the center, then begin stitching with the convex (outward) curve on top, matching the beginning edge of both pieces of fabric:
As you stitch, align both layers by lifting the fabrics and stretching slightly so they are flush:
A little light pressing (with steam) and the seam will lie perfectly flat!
To add one row of apple core pieces to the next, treat each piece the same as you did when adding two single apple core pieces together.
Continue down the length of the strip until both strips are joined.
Once you've mastered the gentle curve of the apple core blocks, the more severe curve of Solomon's Puzzle will be a snap!
