onesie (or shirt) of your choice
fabric for the tie
HeatnBond LITE (iron-on fabric adhesive)
(optional) tie template
thread of your choice
Lay the HeatnBond (paper-side-up) on the back side of the fabric and iron it for 2 seconds in each section.
Do not iron the HeatnBond for too long.
(I ironed for about 10 seconds once and it ruined the adhesive so that it didn't end up bonding at all.)
Draw a tie on the HeatnBond paper.
(You can just free-hand draw the tie to the size and shape of your taste or you can download a template to trace.
There are a few different templates floating around out there in internet world).
I made my template(s) myself by drawing them free-hand on tag board.
I made the one with the separate knot so that I can buy smaller pieces of fabric.
(I guess that makes me cheap).
Cut it out.
Peel the HeatnBond paper liner.
Position tie on shirt then iron (6 seconds).
Sew around the edges of the tie in the stitch of your choice.
This picture shows the settings I use on my sewing machine to create the thick embroidery stitch I usually use:
stitch setting: zig zag
stitch width: 5 (highest)
stitch length: 1.5 (actually the button hole setting)
I will warn that I commonly have issues with bunching, etc. on these settings.
It is so much easier to sew with a longer stitch length (more typical zig zag look) or a straight stitch but I like the thick embroidery look.
Put the shirt on the baby. :)
