I was reading my friend Deece's FB Group Brynwood Needleworks and Carol, one of her followers/friends, was asking about machine applique. She is a long time hand appliquer (?) and was considering stepping out of the box. So Carol, here's a few pictures of machine applique I have done (that I could put my hands on quickly) for you to consider. It's always a matter of personal preference. As much as my friend Deece would gasp, I happen to prefer machine applique. There are times when the stitching just helps add another dimension and finishes the project off..............for me.
This is a tiny applique stitch done with sewing thread. I didn't want it to show as much since the block was meant to look pieced. The picture below is from the same block but I thought it showed the stitching a bit clearer on the white fabric. You could go even lighter in the stitching than this one if you wanted your stitches just about disappear. Aurifil 50 wt sewing thread is what I would use. This block was stitched before I introduced myself to Aurifil thread!
So Deece and Carol, I'm not positive of each of the threads I used on these projects as it has been some time since I stitched them but you get the general idea. The top two appliques were held in place by fusible web. The bottom two appliques were done with the nonwoven fusible interfacing method which is cut away so it is just like hand applique work without the HAND!
By the way, the top two appliques are teapot lids from my teapot quilt. Just in case you were trying to guess what the shapes were!
Hope this helps a bit,
