T-SquareLong straight-edgeUsed to draw straight parallel horizontal or vertical linesImportant to keep the t-square flush with the drawing boardCommon usesRepresentation of property lines, roads, drives, fences, utility lines and for adding boardersAlso used to support other tools such as triangles and lettering templates

Drawing PencilLink between the designers mind and the paperRange from inexpensive wood pencils to the more costly, but longer lasting lead holders

Drawing LeadsHHarder leadsThe higher the number the harder the leadLighter linesLonger lastingBSofter leadsThe higher the number the softer the leadDarker linesEasily smudges and requires more sharpeningNo rules exsist but most landscape designers work with 2H or 3H lead

Lettering Guides or TemplatesUsed to create a stenciled lettering styleTemplate must be matched to the width of the lead tip being usedResults in lettering that is stiff and mechanicalUsed in combination with the T-Square

Ames Lettering GuidePlastic device used with a t-square to produce guidelines for hand letteringCan be set to create lines in varying numbers and varying width that can be replicated endlessly without additional measurementAlso has straight edges that allow it to be used in the actual creation of lettering too.TrianglesHave either 30-60-90 or 45-45-90 degree combinationsUsed by themselves as straight edges or in combination with the T-square to create lines of consistent angles of 30, 45, 60 or 90 degrees

CompassUsed for creating circles, the basis for many landscape features such as plants, patios, pools and lawn areasRemember when drawing circles that the distance between the two legs of the compass should be half the desired diameter of the circleEx: You desire a circle with a 4 diameter, so the compass legs should have a spacing of 2

CurvesHard plastic or flexible plastic supports for curvilinear linesFrench CurvesHard plastic & available in assorted shapesFlexible CurvesFlexible plastic that allows limitless support for the designer as it can twisted into practically any shape

ScaleUsed to represent actual dimensions in a reduced sizeTriangular in shape that provides 6 edges2 common typesEngineers ScaleArchitects ScaleEngineers ScaleDivides the inch into various multiples of 10Permits dimensions to be read as whole numbers and decimal portions

Architects ScaleDivides the inch in a number of ways that permit dimensions to be represented as feet and inches

ErasersPlastic erasers Used the mostKneaded erasersUsed for lightening linesSpecial purpose erasersUsed for the removal of ink or colored marker but do not work as well as claimedLiquid erasersUsed for removing old, dried ink lines or those created by copy machines

Erasure ShieldHelpful when erasing soft B leads or small portions of a line
