I am getting better and better at FMQ'ing. But here's my problem. I am using two colors...top red, bottom black. I am pleasantly shocked and happy that neither shows on the opposite side. However..my problem...the starting and ending threads. I pull the bobbin thread to the top with the top thread before I put the quilt sandwich under the foot. Then, I slide it under, and take 2-3 stitches, and then do a reverse of 2-3 stitches (literally...2-3 stitches, I do it slowly so that is all I do) and the ends are caught and no tieing or unraveling.

However...here is the problem. The top is red thread and the ends look perfect, no black thread to be seen. However, on the backing side... a little bit of the red thread is pulled to the bottom and you can see the red thread. It is a tiny knot looking junction with the black thread. I can't pull it to unknot it, and if I just cut it down...you can still see the red thread. So it look kind of sloppy to have that little bit of red on the black back. I did Northern Star in red and black and outlined/top stitched each diamond portion of the star. I tried to do all the same color with one motion but that bunched up to much in the middle. So I did each diamond shape individually...which means a stop of the red/black thread on almost each diamond shape.

How do I stop this? I know it has been said to pull the threads to one side and tie them then needle thread them into the sandwich, but I can't do that on this....so..what can I do to make the back look nicer? I am planning on putting this quilt (and hopefully others!) for sale in a consignment shop so I want it to look as close to perfect as I can get it!
Thanks for any tips!
