In the Central Museum in Utrecht I visited an exhibition about Blue Jeans. This photo "Horse and Rider" was the eyecatcher and specialy made for the exhibition.
What do you think of a keyboard always at hand?
The jeans made by designer Martin Margiela were rather "casual".
After watching the exhibition you could work with jeans fabric with the help of a seamstress.
There were all kinds of old blue jeans available to use for your own design. I didn't use the oppertunity, but it was fun to watch the exhibition.
sccollections has some nice pictures on his blog too.
