How can I fix this frame?

is this frame metal or plaster might try getting wet sand pressing good side into it to get detail and then pouring plaster into it. for metal you probably need a professional as it is more dangerous

press playdough (dollar store ) onto good portion to make a mold.Fill with plaster of paris , wood putty or similar stuff and paint . grease the inside of mold before filling . invert after it dries .There 's your piece .

Very easy

Thanks I am going to give it a try. :)

There is a product at Lowes called rock hard which my friend has used many times for this same type of thing. It works very well.

Buy a can of Durham's Hard Rock Putty. (Shop around, I found the cheapest at True Value hardware store.) Add water to the consistency of pudding and pour into the mold you made from suggestions above. When dry it can be sanded and carved. I've repaired frames like yours and this works for me.

Thanks, I will see which of the above mentioned products I can get my hands on
