Dig a trench along the top of the slope at least 8 inches deep and 6 inches wide.
Lay the upper end of your straw and jute netting into the trench. The top end should be folded underneath against the soil inside the trench and the rest of the roll should descend down the slope. Staple the blanket to the soil at the bottom of the trench with a staple gun; use one staple every 12 inches.
Fill the trench with soil so that the surface is as level as before.
Lay the next rolls going down the slope, overlapping each other by at least 3 feet.
Put staples through the blanket and into the soil underneath at a spacing of less than 1 foot across the top and bottom. Staple down both sides and the center of all rolls with about 5 feet spacing.
Add further column of rolls with the same procedure, starting at the top of the slope with a trench. Overlap 4 inches for rolls moving across the slope.
