This instructable will also be my entry into the valentines contest. My wife is also pretty geeky so I'm sure she'll love the tentacle heart, but shh! Don't tell her before valentines!
As with most of my project nowadays if you can see it you can buy it, this is due to the fact that I'm currently unemployed and I have a lot of time on my hands, but also because selling little things like this, even with these minimal margins, allows me to save up for workshop improvements. So if you're not creative or you haven't got time to make your own then buy one from me and contribute towards my laser cutter/ leak free shed roof fund.

Step 1: The basic tentacle
A smooth board to roll clay on.
A smooth piece of plastic to use like a rolling pin (clear plastic allows you to see the tentacle as you roll it).
A scalpel or other sharp knife to cut the clay.
A paintbrush, used to create the shape of the suckers.
2 colours of clay, one for the tentacles and one for the suckers
Start with a block of clay, I used sculpey which comes in 12 handy blocks straight out the packet), so I just cut one of those blocks off.
Kneed the clay until it become malleable,
Sandwich the ball of clay under the plastic sheet, keeping one edge of the sheet against the cutting matt, slowly start to roll the clay into a cone shape.
Taking a much smaller piece of clay for the suckers, roll that clay into a thinner cone, this will become the suckers.
Cut this cone of clay into equal width pieces, because each piece has an equal width but slowly increasing diameter the volume gets larger.
I like to arrange my suckers at this stage into rows that will go onto the tentacle, each tentacle has 2 rows of suckers so if I'm making 2 tentacles I would arrange 4 rows. This ensures that the first row of suckers on the last tentacle are smaller than the second row on the first tentacle (if that make sense).
Roll each of these suckers into a small ball shape trying to make them as round as possible.
Press the point of the paintbrush into the smallest ball, it should stick to the paintbrush, then press the ball against the tentacle, it should leave the brush and stick to the tentacle. (further internet research advises doing this stage on some baking paper which helps with the stickyness)
Arrange the suckers in 2 lines along the tentacle, once complete you can bake it according the instructions on the packet.
