not sure if this is the right place to post this thread but I wanted to share with everyone how easy it is to reproduce any knob you may need. first, and most expensive is the mold making kit bought at hobby lobby, it was $41 after coupon and you could make around 100 or more knobs with what comes in the kit and replacement plastic mixture is around $19 with coupon downloaded online.    
First affix the knob or knobs you want to reproduce onto a smooth surface by hot gluing or anything that will keep them from moving.    
Then make a cardboard box around the knobs leaving about 1/2" on either side. make sure it is sealed around the bottom to keep mixture from leaking out.    
then follow mixing directions and pour over knobs, with 1/2" above tallest knob.        
when it hardens, remove knobs and you have a perfect mold. the kit can make a mold to reproduce about 10 to 13 knobs but I wanted a mold for all hex and rosette with any configuration needed so I could pour an entire set at once.
