Blanket Plan and Preparation

Crochet a total of 130 granny squares in your chosen colors.
Arrange the squares into a layout of 13 squares across and 10 squares down.
Place all squares out on a flat surface to determine the final color placement.
Use white yarn for joining the squares and green yarn for crocheting the border.

Assembly Method Joining the Squares

The squares are joined in two stages, starting with horizontal joins and then moving to vertical joins.
A sewing method such as whipstitch or mattress stitch is used to create clean and nearly invisible seams.
The right sides of the squares remain facing outward.

Join Horizontal Rows

Flip two squares so the wrong sides are together.
Work by inserting the needle through the back loops only on both squares.
Pull the yarn through each stitch pair across the entire edge.
Join all 13 squares to complete the first row, then join the second row, and continue until all 10 rows are joined.
