Managed to get this one quilted in one day. Straight line across the grey and straight line vertically for the orange. And fair warning here, I did something that will freak out the purists. I didn't bother sinking the threads where it stopped mid quilt, I just did back stitch!!!
You can see where the grey and orange meet that I've done backstitch rather than cut the thread long and bury it into the quilt. I tried doing the lines as one continuous up, across and down but it looked awful. So I did something I rarely do, I unpicked and did it again. Doing it this way the quilting was all done middle to outside and looked alot better. I just couldn't face all that hand finishing. I've done it on another quilt I did the next day, which has now been washed and there was no ill effects, no fraying at all. So I will probably do it again.
