traditional hand craft and material

After research about Sri Lanka's traditional handicraft and materials, I decide use Lace making as my technical, and use cadjan (palm leaves), bamboo, and brick as my materials.

cadjan Plaited leaves of the coconut palm which are used to thatch roofs in some rural house. In earlier times, cadjans covered less lowly roofs as well.

Bobbin lace (or pillow lace) takes its name from the way it is made: on a  firm pillow to which a pricked-out pattern is tacked and each twist of the bobbins is held in place by a pin.  For all its intricate and elegant appearance, there are only two different movements of bobbins in the formation of the lace: the twist and the cross. 

bobbins type

Roller- many shapes  

but nearly all with a roller embedded in pillow.                            These are good for most continuous laces; like edgings, flounces, trims etc.
