I have used James C Brett Pure Merino and a 4mm crochet hook.

 

The pattern is a variation on the "Red" Triangle on the Woolfest website.  You can use just one colour but I thought it was quite fun with the different coloured bobble.  The pattern as you will see is basically just 3 rows and each time you have a Make Bobble row you increase the number of dcs before and after by 2.

 

 

 

Abbreviations:

 

ch = chain

dc = double crochet

tr = treble

MB = make bobble (work 4 open tr in same st leaving 5 loops on hook, draw yarn through all 5 loops at once)

 

 

 

Ch 3

 

2 tr into 1st chain from hook, turn (3 sts)

 

Row 1:  Ch 1, 1 dc in each tr across, 1 dc in top of turning ch, turn

 

Row 2:  Ch 3, tr in 1st tr (inc made), tr in each dc across, 2 tr in top of turning ch (inc made), turn (5 sts)

 

Row 3:  Ch 1, 1 dc, MB, 1 dc, 1 dc in top of turning ch, turn

 

Rows 4 - 6:  Repeat row 2, then repeat Rows 1 and 2 (9 sts)

 

Row 7:  Ch 1, 3 dc, MB, 3 dc, 1 dc in top of turning ch, turn

 

Rows 8 - 10:  Repeat row 2, then repeat Rows 1 and 2 (13 sts)

 

 

Repeat Rows 7 to 10 until you do:-

 

Row 35:  Ch 1, 17 dc, MB, 17 dc, 1 dc in top of turning ch, turn

 

Row 36:  Repeat Row 2

 

Row 37:  Repeat Row 1

 

This is where my triangle has finished but it is up to you on the size you want to make.
