I am a 4 month old new owner of a pfaff creative vision.......I know there is quite a few of us quilters that embroidery. I am having a tension problem... I have re-threaded, replaced bobbin, changed needles. Followed the troubleshooting stuff, talked to my rep at the sewing machine shop. Gone through the steps to NO avail. Now I am enlisting your help.
The photo is the back of a dish towel. The top is a little better. Working on snowflakes. Any suggestions would be great. The shop is over an hour away... And today is Sunday. Would like to get Christmas stuff done but I've been messing with this for 2 weekends now. I've tighten and loosen bobbin, needle tension, cleaned bobbin area. Even just tried tension in sewing mode and follow direction in pfaff booklet to set. My serger is less of a problem then this machine....sew frustrated!!!
