Step 1: Sheets And Rails
Myrna cut the green rails 3 squares tall and the long width of the base sheet.
Three squares tall and as wide as the base sheet, the center squares will hold the stitches and the top and bottom squares will hold the Letter and Number Cards. The cards slide along these rails to be able to move the numbers around for each month. The 1st of the month does not always start on a Monday.
In the picture below you can see the first rail is sewn right to the edge of the base. The rest of the rails will be sewn in the center to hold cards above and below.
If you sew the first 2 rows from the bottom you will have 10 squares between the stitches on the 1st and 2nd rails. 11 if you don't.
There are 10 spaces between the stitches on all the rest of the rails
The cards are 9 x 9 squares and fit to slide between the rails.
If you sew over 1 under 1 at the end you stitch over 1 under 1 to get a solid line of stitches along the length of the rail.
