Stamps!Stamps!
Creating a patternCreating a pattern• Determine a structure. In
this case, a standard grid
• Determine an interval. (distance, size, negative space)
• Determine a motif. (element, here a pentagon)
• Consider options: rotation, integration, alternation
StructureStructure
Standard Grid
Staggered Grid
The grid can also be comprised of diamonds, triangles, rectangles . . .
IntervalInterval
Options: Options: RotationRotation
¼ turn clockwise
no turns
alternating rows of 1/4 turn and reverse
Linear Pattern
Field Pattern
FoursquareFoursquaress
Options: IntegrationOptions: Integration
Making the stampMaking the stampMotifMotif
It should be asymmetrical to allow for rotation
It should touch (or get really close) to two sides to allow for connection
foursquare
Making the stampMotifMotif
It should not have too much open space to the edges, this will help prevent fouling (accidental inking)
HINT: in this material, straight lines and angles
are easier to carve than smooth curves!
To do:To do:
• Design a motif on paper• Transfer design to eraser and
carve (remove about 1/8th inch or the thickness of a metal ruler
• Create various linear patterns• Create various foursquares• The fourquares are a motif
themselves, later use them to create larger field patterns
