I have owned a GQ1200 mounted on a Inspira frame for about 4 years. I have worked through so many problems each time I load on a new quilt. I haven't found any classes posted to learn about this machine. I just recently found your website when I was having trouble with the needle. Thank you for the idea of HL needles only. I just wanted to know what number to set the tension on. The manual does not tell that at all.
