why yes! i AM making Christmas decorations in January...
i love the simplicity of stamped decorations but i prefer the durability of solid clay. this was a happy compromise
the stamp im using was one of a selection of papermania stamps that i got free with a craft magazine over a year ago...if i remember correctly it was probably why i bought the magazine but you could use anything you fancy.
roll out a sheet of clay (in this case white pearl) and cover/spray your stamp with your preferred release agent (either water or cornflour are my usual stand bys)
place marzipan spacers/ knitting needles (or similar) the same thickness (preferably just under to ensure a nice deep clear print) either side of clay and over the stamp firmly.
carefully remove the stamp and you should be left with something like this..
trim to shape with a tissue blade or craft knife. you can either add a hole to hang it by with a needle at this point or drill one later
bake in the oven at the recommended temperature for your clay for the recommended time. i find once i've removed it from the oven immediately placing it under a flat heavy object prevents any air bubbles which may prove a nuisance later
take some well conditioned clay and using a craft knife smear it firmly over the surface (like buttering bread). make sure you get it into every part of the design.
using your craft knife remove the excess (unless you REALLY like sanding)
now bake again. once cool use wet/dry sandpaper (im using 1000 grit) to sand away the excess clay to reveal a crisp design.
either buff or varnish then string and admire
as always comments or advice are more than welcome
