I'm going to try machine applique and was wondering if I could use regular sewing machine thread or do I need to use embroidery thread? Any tips would be appreciated.

I use regular sewing thread.

I use whatever thread I think will look best.

I use both, it depends on how much I want the stitching to show up :D:D:D

I haven't tried because it's very expensive but I heard that silk almost dissappears, I do use it for hand applique and love it

Me too.

The one I use the most is Invisable thread in either the clear or smoke color.

It depends on what type of applique I'm doing and if I want the stitching to show or not.

If I'm doing a decorative stitch like blanket stitch, I'll use a heavier cotton thread so it shows up more. For a satin stitch, I want the threads to lie nicely next to one another, so then I might use a shiny polyester like Isacord.

If I'm doing the invisible applique using a blind hem stitch, I may use a finer polyester like Sew Fine or Bottom Line, or if I don't want to change thread colors then a clear polyester thread like Monopoly.

Not a very definitive answer, was it??? LOL

No police here. I use whatever looks good and doesn't breAk. Regular thread, maxi lock, embroidery thread. Some have even used a needle with a huge eye and a couple strands of floss (not myself but I've seen and heard of it)

I have used both Embroidery and regular. It is cheaper to use regular and I don't have to set up my thread differently.
