Bias: take a square of fabric..fold bottom right to top left making triangle shape..then fold top right of triangle and bottom left of triangle to overlap..cut fold off about 1/8 inch.. then cut strips..I cut 1 1/4 in..wrong sides together..sew seam scant 1/4 in...press flat with seam in middle of back.. practice folding technique using square paper napkin first...hope that helps....judy
