void SelectionSort(int a[],int size)

{

       for(int i=0;i<size-1;i++)

       {

               int min=i;

               for(int j=i+1;j<size;j++)

               {

                      if(a[j]<a[min])

                      {

                             min=j;

                      }

                }

                if (min > i)

                      swap(a[i],a[min]);

Knitting Painting 8" x 10”

    I always want  to try different styles of knitting works. This painting is 8" x 10". Before started, I went to the frame store to measure the size of picture I was going to make so I can pick a nice frame later. The background is simple purl needle knitting pattern. The girl, flower and butterfly are made by crochet.
   

    Actually the initial idea in my mind is to make the girl holding an umbrella in the rain. But the handle of umbrella didn't fit the girl very well. I decided to use hat instead.   

    I named this painting "Waiting for the wind". Just the first name pop up my mind. Wind is complicate, it can be good or bad. In a sunny day, a girl looked out into the field beyond view, the bird, the cloud, the butterfly and the flowers. Everything is quite and beautiful. She is waiting for something, something could be peace or challenge.

    Just moved to new place, wish I can have a new life, just like this girl
