“Tlysau Celtaidd” is Welsh for “Celtic Jewels”.

For this square I used DK yarn and a 4mm hook, but you can use any yarn or hook suitable for your project. If you want to make this to fit in with a BAMCAL¹ project, please note that I have made this with the same yarn and hook as I do for the BAMCAL “six inch” squares, which are designed for Aran/Worsted yarns. This comes out for me at roughly the same (smaller) size as my BAMCAL “six inch“ squares (very slightly over 4½ inches). However, it is a little larger so you might want to go down a hook size if you want it to fit with others.

This pattern is available in UK and US terms. Please let me know if you have any problems with the pattern (downloading, opening, reading, making the square …) and if you spot any errors.
