RSC Yellow Celebration week 26

Angela chose the colour yellow for June, and put up a number of sampler blocks. This week I made three, and as far as I know I'm up to date on yellow.

Here are my three yellow blocks:

Clockwise from top left: Economy , Fiesta (hence the celebration) and Butterfly

I'm really pleased with the Economy block which had always frightened me somewhat because of the complex maths (Pythagoras and all that jazz).

Last week Angela posted a link to a chart with the calculations for triangle sizes, and gave her own rounded up sizes. However I recently downloaded a free app for my iPhone called "QuiltingCalc: The Quilter's Little Helper" (for iPhone or Android) from Robert Kaufman Fabrics, which calculates the sizes for you. I used this, although it was necessary to calculate in two stages: firstly the triangles to make the outside square, and then the triangles for the middle square. In other words you calculate from the outside inwards, which is what we always do anyway!

This app not only helps in calculating economy block sizes, but also backing and binding. If you have a smartphone or tablet, I would recommend you take a look. It's free!

I think I would like to mark the halfway point in this year by taking a photo of all my RSC blocks so far and posting it next week. Does that seem like a good idea for everyone? As we still have a couple of June days left we might still be making yellow blocks over this weekend, or we can use the next week to catch up generally.
