Entrelac scarf

I have joined one group on facebook. They decided to do an entrelac scarf. On the same time, i wanted to give something for a friend. So i have decided to do this scarf. I was so excited to make this scarf. I started from the bottom. That means i need to cast on 210 stitches!! Which are 21 triangles x 10 stiches per tier. But it is really exciting when the tier is reduced as you knit to the top cause it is a triangle scarf. I have used almost 2 skeins of baby acrylic yarn and stranding 2 yarn together using 4.5mm needle.
