Silk thread in bobbin
 

I am going to be using #100 silk thread (top of machine) to FMQ a silk necktie wall hanging. Can I use silk thread in the bobbin or is there a better choice? Thanks for your advice!

yes you can but you may not have to you could use poly embroidery thread it would be cheaper. I have used the silk in the bobbin and on top no one will see if you make a mistake it is so forgiving.

often you have the best luck when your bobbin and top thread are the same- much easier to have equal tension.
if you find it is not working for you you could try a bottom line thread- or other bobbin thread (they tend to be 60-70 wt)
i use silk thread alot- love working with silk thread- and my machine loves silk thread- but not all machines behave the same when it comes to threads- best to wind part of a bobbin & give it a try on a practice piece---make sure you use the right needle for your thread/fabric choice- you don't want a big needle when stitching silks....or using silk thread. and silk is VERY STRONG thread! many quilters use silk thread to quilt king sized quilts- it is wonderful for detail quilting....and holds up well.

I also thought silk thread was very strong until I used it to bind a quilt & it came all apart. Has anyone else had this experience. I had to re do the entire binding - not fun.

I just finished a machine quilting a quilt with silk thread in both top and bobbin. My machine loves it and I use it frequently.

I would not use it for hand binding though.

I use silk thread for most of my fmq. It makes my quilting looks much better (can't see the mistakes that much). I use Bottom Line, Sew Fine, Finishing Touch, Invisifill, or Glide, in the color to match the silk thread in the bobbin. The new thin threads available now are really just as nice for machine quilting as the silk threads. Batting makes a big difference when using silk or thin thread. Wool batting works best for me when using thin thread for machine quilting.

Here's a link to the guru on quilting with silk thread. I get all my silk thread from her because she sells it in big spools. She recommends a Mettler embrodiery thread for the bobbin.

Good luck!
