Rita,
Your quilt is wonderful! I am impressed. I think you should consider designing quilts professionally and selling patterns. You are definitely gifted in this. Maybe start by submitting articles to quilt magazines.
By the way, I agree with you about the Bernina walking foot. The dual feed is nice and it helps with many feet, but the dual feed is just not the same as the walking foot. I bought mine about a year after I bought my 830. It was expensive but well worth the money.
The interchangeable soles for the walking foot are very useful. When I make a queen-sized quilt, I usually start by stitching in the ditch with the walking foot with the stitch-in-the-ditch.
In another thread, you mentioned the Bernina bobbins. I have lots of generic bobbins for my Janome, but sure can't buy a lot of large Bernina bobbins, as they are not inexpensive. If I have a lot of thread left on the Bernina bobbin, I don't necessarily want to throw it all out, but I also want to free up the Bernina bobbin for the next thread I need.
Tip: When I am finished with one thread on the large Bernina bobbin, I rewind the thread left on the Bernina bobbin on a smaller generic bobbin. I usually rewind them with the Simplicity Side-Winder.
Then I attach the generic bobbin with the rewound thread to the matching spool of thread.
This is a tip I learned from a fabric shop owner. She said to buy some heavy flexible plastic - the kind sold for covering tables, etc, at JoAnns or Walmart. Then cut the plastic into strips.
Hold the bobbin flat next to the spool of thread and wind the strip of plastic around both a few times. The static electricity holds them together.
This keeps my threads and bobbins organized and neat. No loose threads.
If the plastic strip stops clinging to itself, wash it with soap and water, and it will cling like new again.
I cut a batch of strips with a rotary cutter with an older blade that I am about to discard, and wind them in a big roll that I keep in my sewing machine drawer next to my bobbins.
Hope this makes sense. If it will help, I will try to take a picture and post it.
