Make the burlap foundation for the chart. Cut burlap to 13 inches wide by 63 inches long. Fringe 1/2 inch on 2 long edges and 1 short edge of the cut burlap.
Fold the bottom (the short fringed edge) of the burlap up 5 inches and press a crease to create a small pocket. Temporarily seal the edges of the pocket closed with a strip of double-sided iron-on adhesive tape (this will also keep the edges of the pockets from fraying).
Reinforce the pocket sides with a backstitch, using embroidery thread. Sew a seam down the middle of the pocket the same way, to split the pocket in half and keep it from sagging.
Create the iron-on pieces. Iron an 8 1/2-by-11-inch piece of heavyweight double-sided iron-on adhesive onto a slightly larger piece of muslin. Trim the fabric around the bonded adhesive to create a 8 1/2-by-11-inch piece of paper-backed muslin, which you can feed through your printer (like a regular piece of letter-sized paper). Repeat to create 9 pieces of printable fabric.
Download and print the templates for the height markers, watermelon, tomatoes, stone walls, pumpkins, peppers, broccoli, barn 1, and barn 2 (see Tools and Materials) on the printable fabric sheets you have created. Cut out all pieces.
Peel off the paper backing and iron the 2 pieces of the stone wall onto the two burlap pockets at the bottom of the chart. Iron the barn to the top of the chart, matching up the halves and aligning the tip of the roof with the top of the burlap chart. Cut off the excess burlap triangles above the roof of the barn.
Lay out the vegetable patches on the chart between the barn and the wall, alternating sides. When you are happy with the layout, peel off the paper backing and iron the patches onto the burlap.
Back a measuring tape with double-sided foam tape. Affix the measuring tape to the center of the chart, aligning the 11th inch with the bottom of the chart.
Back the wooden supports with double-sided foam tape and affix to the back of the chart; one at the very bottom, and one along the bottom of the barn. Add a grommet to the top of the barn within the circular hay loft opening, if desired.
Peel the paper backing from the printed vegetable height markers, and use the same process as before to iron them onto a craft foam sheet; however, make sure that your iron is set on low heat to avoid melting the foam. Cut out and store these markers in the pockets of the chart. When measuring height, use a fabric pen to write the child's name and date on the marker. Affix the marker to the chart at the measured height with foam tape.
