Building Blocks 2 - outline

I decided to have black outlines to all of the blocks in order to help distinguish the different areas and used the recommended technique for transferring patterns from a page to fabric - sewing running stitch through both paper and fabric then tearing the paper away. However, there was a problem. Although I thought I had lined up the vertical lines on the paper pattern with the grain of the fabric I apparently wasn't accurate enough.

You can see how the verticals indicated by the tacking are very slightly diagonal and the boxes ended up rather uneven.

Eventually I just used the tacking as a vague guideline for the height and width of the blocks but worked with the grain of the fabric for verticals. This is what I ended up with:

 Since this is just an exercise it is bearable and I won't start again but it is definitely irregular so I need to find a more accurate way to transfer designs to fabric. I had hoped that by drawing the design as a geometric grid on paper first I would be able to make it uniform but I think for future reference it would be better to work out the angles and sew regular straight line shapes onto the fabric direct. I'll have another go at the tacking technique some time I'm using a more irregular or curved shape as it may just be that I need more practice..
