Despite my good intentions I haven't managed to finish my 9-patch blocks on time; I was away at the week-end so lost some time but daughter's 30th was more important than 9-patch blocks
What I have managed is to take things slowly and trying to be a bit scientific in my approach. I have tried with and without starch, my "travel" machine and my 9 mm embroidery machine with different feet and different threads all with varying results (still got one more variant to try). A lot of frog-stitching has taken place but I have learnt so much along the way.
One very important thing I have learnt, which is probably old hat to all the very experienced quilter here, is that you have to stick to one ruler brand when cutting and sub-cutting. A small ruler went out with the rubbish yesterday because it did not give the same 2 ½" square as my other rulers. I have also found that changing thread from 50 weight to 60 weight influences the outcome. I am keeping a diary to refer back to when this sampler is completed. Today I hope to do the last "experiment" and then decide which combination I like the best (which will certainly not involve my embroidery machine which is wonderful for embroidery, appliqué and decorative stitches but NOT for piecing when I'm in charge
I look forward to see how I fare with the next lot of blocks as I have always had huge problems with HSTs and Pin-wheel blocks send shivers down my spine
