Thanks to my left over acrylics from my previous headband project, I don't need to go and buy these beads. I took out my cardigan from wardrobe, gather all my things- scissor, acrylics beads, needle and thread and I start sewing from shoulder joint up to the midst of shoulder. I don't put too many as I don't want it to look heavy. I want it simple and casual.
Now I don't have a funny looking cardigan anymore.
