Step 1: Cut two pieces of 28×28 cm cloth. The second step is to erect the front of the cloth and put away the lace. The lace should be folded at a small right angle at the corner, so that the lace at the corner can be turned out well when turning the handkerchief. Sew the lace full circle. Step three. Cover the newly sewn lace cloth with another piece of cloth facing down, and the faces of the two pieces of cloth are opposite. Step four. Take the newly sewn thin cloth to the sewing machine for sewing. Note that the stitched side is facing up, and then sew along the seam. Finally, remember to leave a small hole.
I sewed it when I was watching TV, and I sewed it tightly if I was not careful. But I opened a small hole again, hehe, so I want to remind my sisters not to make the same mistake as me. This seam is used to turn the handkerchief upside down. Turn the handkerchief upside down, and then sew the small holes with hidden stitches. It's perfect. You can't tell.
