(if your using clay simply replace the word wax with clay ;) ^^ )

allways I start by making a pattern. this time 3dimensional. it´s simlpy 2 sketches barged into each other and fixated with wax (pic 1)

I stabilized the paper pattern with more of the very strong wax.

then I roughly filled up the gaps with weaker wax. I used way more wax then necessary to have enough wax to grate away. after the pattern is filled up, I stared scratching the wax to a rough bottle shape (pic 2)

but the shape of a bottle is pretty hard to reproduce.

so I used half of the cut out from the pattern to reproduce it. I circled around the bottle with the pattern and scratched way the wax untill the gap bitween bottle and cutout is gone (pic 3)

(tip: you can polish wax with a wet spong or cotton)

finish of the modellation is a tiny bottle cap.

this is simply made from a very thin wax board I bend over the bolltes neck (pic 4)
