Brazilian embroidery- Comparing Rayon and Perle Cotton

I was playing around with one of the free patterns from BDEIG site . The first time around I stitched the two leaves,pistils and both the double cast on petals on either side.But when it came to completing the remaining instructions, I changed my path and modified the flower to this.

Just wanted to see how the flower looks with the changes. Not bad,right? May be this flower too has a name in the BE dictionary.

I started again the second time, fully intending to complete the flower according to instructions.Once again had a brainwave midway through - why not show the difference between embroidering with Rayon and Perle cotton in the same design? Wouldn't it convey the message more clearly than mere words? Here's the result :

Can you distinguish between Rayon and cotton?

For the comparison to be effective ,I used the same shade of Lola and Anchor Perle cotton . Many a times this question is asked by first timers - why Rayon ?,why not Perle cotton floss?The main reason behind this is the twist of the threads - Rayon is Z twist while Perle cotton is S twist . And the next reason- have a careful look at the pics below.Do you think the sheen and texture of Rayon could be compared to those with cotton in any way? Isn't the difference obvious?

Extreme closeup!!

I tried the same technique with another color and type of rayon thread and an almost similar shade of anchor perle cotton. No prizes for guessing which is rayon and which is cotton.

It is this difference in looks which prompts all Brazilian embroidery experts to insist on rayon threads and not cotton threads. For Indians, a suitable subsitute would be cone threads and silk.

Wishing all my friends and readers in the blogland a very Merry Christmas and loads of
Love,luck and sunshine in the coming year,
