I am trying to create a blend for the rivers in Illustrator CS. How can I acheive this when the river is not a regular line like the first drawing and more like the second drawing. It is an irregular shape and the number of point is not the same on the north shore and the south shore. Creating regular blend is easy but I do not seems to get it right for the second draing. Somebody suggested I import the layer in Photoshop and place the result back in Illustrator. It may work but the file size would be too big I think.
Thaks for any idea.
