I returned to work on my DP4 now called Summer all year long and had lots of trouble - put it down to wrong thread weight, got more of the original thread weight but it wasn't resolved. I played around with thread tension - better but not perfect. I changed to a metallic needle hm not really different. Tonight I rumaged through my various boxes on my (very dirty!) windowsill and found some more Universal needles. I put a new 70/10 in and voila things just worked!!! I managed to fmq another oven mitt without missing stitches, then moved over to the D4P - barely skipped any stitches!
Of course I have read many times to change your needles but I have never paid much attention. I usually change a needle when it's bent or breaks - not any more!!! But is there a reliable way to tell when the needle needs changing? Please let me know!!!
Below some quick snap shots - close ups of DP4 feathers with and without issues and the oven mitt. Please excuse the quality, just some quick shots on the iPad, I couldn't wait to reveal my new revelation (and with that my being a slow learner lol) to the world!!!
