Patterns

It's been a rather cold weekend and the cold spell is apparently not over yet. There was however a bit of sun this afternoon and when I got into my car to do some grocery shopping I saw the pattern the remaining snow and the roof tiles made. There are diagonals everywhere ! I'd like you all to find diagonal patterns for his coming Abstract Thursday's challenge :-)
The tag will be AT143.

Thanks so much for all your entries for last Thursday's challenge, most of you had tried their hands and cameras at abstract macros, and did very well ! Find them all here.
As usual I had a tough time choosing just 5 specials of the week.
Here they are in no particular order:
Cheryland    for the wonderful details of a bougainvillea bract
muddyshoes   for a ink-painting-like silhouette
Stella2     for a cascade of petals
Arteegeedee   for a natural pockmarked surface
Doylee22   for a sharp-teethed shell abstract

Thanks so much for all your entries and for joining in with the challenge, looking forward to your diagonal patterns !

And thank you for the kind comments and stars for yesterday's wintery scene !
