Colored pencil, 9x12. This one was MUCH more difficult than I anticipated. I've spent a frustrating week on it and glad to be done. The reference photo I took was actually of the vase sitting on my kitchen floor--white tiles with black grout. I didn't want the lines in the final drawing, so I had to do all the reflections in the glass while leaving out the black lines. In some places (particularly in the cut glass areas) it was almost impossible to tell what would be happening in a certain space if the black line wasn't there! Whew! Moving on...
