Hi Klara
Welcome to Cute. Sorry I cannot answer your question but someone will be able to I am sure
Happy sewing

Klara, I haven't done this yet but have been planning to do a custom tie for my dear hubby for Christmas. Recently one of his ties accidentally went through the laundry so I had the opportunity to put it back together. I learned they are very basic and nothing to fear.

When I embroider the tie, first I will open the stitching on the backside so I can lay it flat. Mine are silk so I will use a light to medium mesh stabilizer. I do not want to hoop it so I plan to use the lightweight tearaway sticky type in the hoop. I normally use a water soluble topper but on the silk I won't, instead opting for a very light tearaway. Mark my placement, stick it and stitch it. When I am finished just hand stitch the backside and I am done. That's the plan but if there is a Cutie who has done this, I am certain they will share with both of us their experiences. Welcome to Cute and Blessings!
