Summarize the following:
The inner section is closest to the center hole of the wreath and designated by the 2 innermost wires. Place your non-dominant hand underneath the burlap and press it upward through the inner section. Continue feeding it through by pulling it with your dominant hand until the loop extends about 2 to 3 inches (5.1 to 7.6cm) upward. Since there are 2 layers, this totals about 4 to 6 inches (10 to 15cm) of burlap. Use your first 4 fingers as a guide for loop size. If the loops are loose around your fingers, pull down on the burlap until it fits snugly over them. Increase loop size for a fluffier wreath and decrease it for a tighter wreath.

Summary:
Press the first 4 to 6 inches (10 to 15cm) of the burlap through the inner section.
