When Bonnie released the second
mystery clue on Friday night, it gave me some thinking to do. If you saw my post last week, you may remember I changed the size of the first pieces to make them easier to cut in metric measurements. But in making the first part easier, I had unknowingly made the second part much harder! That's the danger of playing round with a mystery.
On Saturday I met up with some quilting friends, and ran my maths past one to see if she came to the same figure as I did. She confirmed that to fit with my first pieces, this week's would have to finish at 10.666667 cms (and be cut at 12.1666666 etc). Well that wasn't going to happen!
One option was to go back to using inch-equivalents (ie 2.5cm for an inch) and cut down last week's pieces to suit. But this would mean cutting at quarter centimetre measurements, which is what I was trying to avoid in the first place. The second option was to use a different measurement which would be easy to cut for both last week and this week, and re-make last week's pieces. Re-making is not such a big deal, as I am only making a quarter of the specified numbers at this stage. But larger pieces might result in a chunkier-looking quilt, which might not be good. After lots of thinking I decided on the second option, using 3cm per inch. This will make my pieces 20% larger than Bonnie's. I think I can live with that.
Much easier to line up my strip with the 12cm mark than the non-existent ten-and-two-thirds line!

This is my metric equivalent of the Companion Angle ruler Bonnie uses. It's the first time I've used it to make a shape like this. Unless you have red-green colour-blindness, you will notice that I am using green where Bonnie has red.
Feeding the bits through the machine:
Once they were all done, I remade the half-square triangles from last week:
and cut the extra squares in brown (my constant) and grey (for Bonnie's black). Now I'm ready for the next clue!
When this week's link-up goes live, I will add the link to this post so that you can easily go and check out everyone else's progress.
Here's the link-up. Although I can't add my link to it for some reason. I've tried about 10 times, but it never loads. I'll try again tomorrow some time.
Added later: Hooray! It worked this morning.
I'm number 70 this week. Something must have been deleted, I'm 69 now.
