I have a new Handi Quilter. I purchased some thread from Filtec last year at the Houston International Quilt Festival. This thread is made in the USA and sews beautifully. I use it in the bobbin and as the top thread. Wonderful color selection and hardly any lint in the bobbin casing. You can go online to order. I buy the large comes with 5500 yards of thread. My two friends with the sweet 16 also love this thread.
Also love Glide thread for tip and bobbin.
