Each slot on the stitch path represents 3 stitches and there are 36 slots times 3, which equals the 108 stitches on a baseball.

Step 1: Link to CriCut Design Space to Cut Pieces or Print a Set of Parts to Be Cut Free Hand See Step 7

The pattern for the baseball was designed in AutoCad and up loaded to CriCut Design Space. You will need a CriCut Explore or Maker to cut the pattern. Click the link below to connect to the pattern in CriCut Design Space.

The pieces are cut from light weight 60 lb. card stock. You need 1 red sheet and 5 cream sheets of 8 1/2 x 11. You will have enough pieces to make 2 baseballs.

If you don't have a CriCut and would like to cut a set of parts free hand, see step 7 below.

Assembly helpful hints:

  • Make sure all slots are clear of chaff and open
  • Layout the pieces as shown in the photo above
  • It might be easier to interlock the piece on one half of the ball at a time
  • Face the numbers on the interlocking pieces away from the center so they will be hidden when finished

Step 2: Assemble the Core of the Baseball

  • The core is made with two red pieces and one circle piece
  • Place the circle piece on top of the red piece marked "This Side Up"
  • Interlock the slots and rotate to align
  • Turn the red piece marked "This Side Down" over and place on top of the circle piece
  • Interlock the slots and rotate to align, this will creates an X
  • Carefully fold both half circles of the top red piece marked "C" to the center
  • Flip over and carefully fold both half circles of the other red piece marked "C" to the center
  • Open each red half circle about a third of the way
  • This creates the stitch path and the core for the baseball

Step 3: Interlock Pieces #1

Pieces #1 interlocks in the slots on each side of the center marked "C". Carefully wiggle and bend as needed to line up the slots.

Step 4: Interlock Pieces #2

Pieces #2 interlocks in the slots on each side of pieces #1. Carefully wiggle and bend as needed to line up the slots.

Step 5: Interlock Pieces #3

Pieces #3 interlocks in the slots on each side of pieces #2. Carefully wiggle and bend as needed to line up the slots. These pieces are a little more difficult to line up.

Step 6: Interlock Pieces #4

These are the most difficult pieces to line up. Pieces #4 interlocks in the slots on each side of pieces #3. Carefully wiggle and bend as needed to line up the slots.

You are finished

Step 7: Cut Set of Parts Free Hand

Open each image in a new tab and save to a file. Open images in the file and print them on an 8 1/2 x 11 60 lb card stock. Carefully cut each piece with an x-acto knife and follow the assembly steps above.

    When studying the stitch path of a baseball I found that there are two critical dimensions other than the diameter. If you cut a sphere exactly in half and draw a square in the circle, the corners of the square are the tangent transition points of the stitch path. Now draw a line between the narrowest points of the path. The end points and the corners of the square create 4 planes that describe the stitch path. see photo
