Red onion dye

Magic- red onions and silk combination makes gold! It was my first try to dye silk. 

I finally found the perfect aluminium pan and I found Alum (in dutch it's Aluin). I soaked the silk in a mixture of almost three litres of water with one tsp alum and 1 tbsp kitchen soda. 

I soaked the red onions skins in water, heated it two times and left it overnight. Before I added the silk to the dye I removed all the skins. I heated the dye and left it overnight. The next morning I hung it out to dry. When it was dry I put it in a salt/vinegar solution for a few hours. After this I washed it in the machine and hung it out to dry. I was so surprised by the result, it felt like magic.
