Sorry I didn't get back to you sooner. I would try the micro tec needle maybe a size 60 or 70. they have a sharp point but are very slim and nice for many different fabrics such as satin. I use them for piecing in quilting and such but when they are in the machine and I need to do other sewing I've used them with no problems. Make very nice seams. Schmetz makes them. good Luck
