Granny Triangles - my way

Many of you asked me how to make the triangles for the bunting in my previous post. Some of you asked if there is a pattern for it. There might be a pattern for it in many places, as it is a very basic pattern. Same as in a granny square, but you work three sides instead of four.
Here is how I make them.

Ch4, sl st to first chain to form a ring


First round

Ch2(Counts as first dc. I always ch2 for dc instead of ch3 because I find it balances the height better.)
2 dc, ch2,3dc,ch2,3dc,ch2, join to top of first ch2


Second round

sl st in the next 2 dc (I sl st in the back of the chain)
sl st into ch2 space.
Ch2,2dc,ch2,3dc.
*3dc,ch2,3dc in the next space*
Repeat *-* once more, sl st to top of first ch2

Third round

sl st in the next 2 dc
sl st into ch2 space.
Ch2,2dc,ch2,3dc.
*3dc in next ch2 space
3dc,ch2,3dc in the next space*
Repeat *-* to finish the round and sl st to top of first ch2.

Repeat third round till the triangle is as big as you want.
Please feel free to tell me if there are any errors or confusions.

I have added small metal bells below each triangle. So now they look pretty and sound very good too!!
