I’ve seen a lot of people complain about buttonholes on thick fuzzy fabric so I thought I would share a trick that works for me. Sulky Water Soluble Stabilzer works wonders and makes smooth machine buttonholes.
1) I take a long strip of stabilizer and just wrap it around (front and back) the entire area that I’m going to stitch buttonholes on. I pin it in place and them mark my buttonholes with a pen.
2) Stitch buttonholes using your machine instructions.
3) Rip away Sulky, and wipe with a wet cloth. Finish your buttonhole however you normally do- clip, seal with fray check, etc
4) Voila! Clean smooth buttonholes on thick, tweedy fabric.
This is also the method that I used to make the buttonholes on my Boyfriend Cardigan which was sewn with a thick sweater knit. I haven’t had this method fail me yet.
