These half chained cross stitches are done in yellow perle 8. I made a normal half cross stitch and started the chain stitch at the centre of the stitch. From a distance it looks like a Palestrina stitch. I like this variation too!
This variation is done with perle 12 and 2 mm beads. I put the bead on the thread before I started the stitch, so it's on the first half cross stitch. I made the chain stitch around the bead.
