Ties are a great idea to give to a baby boy. They look so cute with them.
Sharing the Wealth has a very good tutorial to make one. Here comes my explanation.
As a first step print the template that is found here.
Cut your main fabric and some other fabric that will go in or behind your tie, in my case it is a white fabric.
With the front sides together, sew the top and bottom edges only, leaves the sides open.
Turn your fabric over, It will look like this. Remember that the sides are open.
Now I fold it in half lengthwise and sew, your main fabric is inside.
Open it and iron the seam that will later be turned outside
Cut a piece of fabric approximately 2 3/4in X 16in, this depends on the baby or child for whom you are making the tie, accommodate it according.
Sew the long side and turn it over. You have a strip like this. Tuck the edges of the sides and sew them to close it.
Now let's make the knot for the tie. Place the tie on the strip as shown in the picture.
Take the back and cross it over like this.
Then fold it back and up.
Now fold it to the front and pass underneath the front strip to form the knot.
Take the piece that is left in front and then slide it behind (It sounds weird but it works). Arrange the knot until you're happy with it.
Finally give the know a few stitches from behind to prevent movement or it coming apart. You can put velcro, elastic, or buttons at the bottom of the strips to close it.
