alphabet 

blocks to stitch text (currently a-z and space). Uppercase characters are converted to lowercase. All other characters are ignored.

All blocks can be found in the 'Variables' section.

If you want to use the font-blocks just open my project, select 'Export blocks...' from the files menu and download the blocks. Then open your project and select 'Import...' from the files menu and upload the blocks in your project.

2018.05.17 added sensible default values for font blocks
