In the second part of the instructions, we will show you how touse the template to draw various designs, from simple to intricate. The best way to follow these instructions isto read from beginning to end and try each example, since the instructions start simple then gradually progressto a higher level.

A) Draw a Downwards Curved Scallop

-1-

To draw a scallop with a desired width of 14" and aheight of 3", follow the following steps:

Note:• The desired scallop height is the difference between the long point and the short point measurements.• The Scallop Template can be used to draw scallops on either scrap fabric or paper. Avoid drawing designs directly

on expensive fabric, since mistakes can be costly and pin holes are not desirable. Make a pattern on paper, thentrace on to fabric instead. Use masking tape or push pin to tack down the fabric or paper, so it will not shift whenyou are drawing.

• Template should be used on a worktable with a surface which can be pinned into.

Step 2 On the template, find the black line. Align itwith the straight line drawn in Step 1.

On the template, find the red line with thedesired scallop width (14"). Place the crosspoint of this red line and the black line on thecenter mark drawn in Step 1.

Step 3 Along the red line labeled for 14" scallop width,find the desired scallop height (3"). Stick apush pin through the hole next to the 3" markinginto the worktable.

Step 4 Put a pen through the hole marked “Pen”, anddraw along the direction indicated by the blackarrow while rotating the template.

Step 1 Draw a 14" straight line for the width of the scallop.Mark the center.

C) Draw a Half Scallop

-3-

The steps for drawing a half scallop are very similar tothose for drawing a full scallop. Here is an example ofa half scallop with a half-width of 7" and a height of 4".

Step 2 Align the black line on thetemplate with the half-widthline. Along the black line, findthe red line with the desiredscallop half-width (7").Notice this is the same redline for a scallop width of 14".Place the cross point of thisred line and the black line onthe center mark.

Step 1 Draw two straight lines that make a right angle.One for the scallop half-width, and the otherthe scallop height. The center point is the pointwhere two lines meet.

Step 3 Along the same red line, find the desired scallopheight (4"). Through the hole next to the 4"mark, stick a push pin into the worktable.

Note: To draw the opposite side of the half scallop, follow the same Steps 1 through 3 as above. Then, insert apen through the hole marked “Pen”; rotate the template along the arrow direction until pen meets the height line.Draw the curve while continuing to rotate the template.

Step 4 Insert a pen through the hole marked “Pen”,and draw along the direction indicated by theblack arrow on the template, while rotating thetemplate. Stop when the curve meets the heightline.

C) Draw a More Intricate DesignWith some practice, one can use the Scallop Template to draw more intricate designs. It will be a good idea tomaster the simpler designs first before trying this type.

Step 2 Mark the center points for each scallop.

Step 3 Draw the first downward scallop with a width of 8" and a height of 21/2".

Step 4 Draw the second downward scallop with a width of 12" and a height of 31/2".

Step 5 Turn the Scallop Template around 180°. Then draw the two upward scallops witha width of 8" and a height of 21/2".

Step 1 Use the measurements in the picture aboveto draw straight lines for scallop widths andhalf-widths.

Step 2 Mark the center points for each whole orhalf scallop.

The asymmetrical scallops A and B can be regarded as each made of two half scallops. To clarify, we colorcoded scallop A and B in the diagram above. A half scallop with a half-width of 3" and a height of 11/2" (in black),and a half scallop with a half-width of 9" and a height of 2" (in light blue) make up scallop A. Scallop B is madeof a half scallop with a half-width of 8" and a height of 2" (in red), and a half scallop with a half-width of 4" anda height of 3" (in dark blue).

Step 6 Draw the straight line segments. Then fold the pattern where indicated and duplicate the rest.

Step 3 Draw all the half and full scallops withdownwards curves: a half scallop with ahalf-width of 6" and a height of 3"; a halfscallop with a half-width of 8” and a heightof 2"; a half scallop with a half width of 4"and a height of 3"; A full scallop with a widthof 8" and a height of 3". Make sure to usethe correct center point for each scallop.

These three points canbe smoothed out.

Step 5 Draw the straight line segments.

Step 6 Fold the pattern where indicated and duplicate the rest.

D) Refine a Quickly Sketched Design

Step 2 Draw straight lines for scallop widths A and B.Measure the widths and mark the center marks.Measure the scallop heights. Let’s make scallopsA and B the same size: 4" width and 11/2" height.

Here is a design quickly sketched with pen and straightedge. The sketch is rather rough, but one can use thescallop template to refine this sketch.

Step 3 Draw scallops A and B, both with a 4" width anda 11/2" height.

Step 4 Draw and measure a half-width for half scallop C.Mark the center point and measure the height.Then draw the half scallop C with a 10" half-widthand a 31/2" height.

Step 1 Notice there are two upward curved scallops (Aand B); one downward curved half scallop C anda sideways curved half scallop D.

Step 4 Turn the template around 180°. Draw thehalf scallops with upward curves: a halfscallop with a half-width of 3" and a heightof 11/2"; a half scallop with half width of 9"and height 2".

Step 5 Since the half-width is always the same orgreater than its height, half scallop D can beregarded as a half scallop curved sideways.Measure and draw the half-width. The half-width is 21/2". Mark the center point andmeasure the height: 2".

Step 6 Turn the scallop template around by 90°. Drawhalf scallop D with a 21/2" half-width and a 2"height. Use a straight edge and draw the straightline segments. With a pen, draw over to smoothout any abrupt points.

Step 7 Fold the pattern where indicated and duplicate the rest.

E) Enlarge a Design from Books or Magazines to the Custom Size

Step 1 Assume a cornice board will be built according to thedesign from a drawing shown below. The width of theactual cornice board is 72", or the half-width is 36".Measure the width of the drawing below. It is 31/4".

Often, one needs to enlarge a drawing or photo frombooks or magazines to the actual custom size.

Using our Picture Enlarger (DYC11), align 31/4" on theinner wheel with 36" on the outer wheel. Do not let thewheel move.

Step 3 On the Picture Enlarger (DYC11), make sure31/4" on the inner wheel is still aligned with 36"on the outer wheel. Convert each measurementin the picture to the actual size. For example,for half scallop A (in black), find 13/16" on theinner wheel (in blue color), the actual half widthis about 9".Due to the measuring errors and approximations,some adjustments may be needed to make surethe actual dimensions add up to 36" wide.

Step 2 Notice there are mainly four half scallops in thedesign. At each scallop, draw scallop half-widthline and mark the center. In the diagram at theright, each center point is indicated by a letter(A, B, C and D). Measure each scallop widthand the distance from each other. For betterillustration, each half scallop is color coded.For example, the half scallop C (in red) has ahalf-width of 5/16" and its center is 5/8" to theright and 7/16" above the center of the halfscallop B (in light blue).

Step 4 On pattern paper, draw the straight lines forthe half scallop widths using the actual customsize. Mark the center points.

Step 6 Draw each half scallop using the actual halfscallop width and height.

Step 7 With a straight edge, draw straight linesegments.

Step 8 Fold the pattern where indicated and duplicate the rest.

Step 5 Measure the height of each half scallop in the original picture. Use the Picture Enlarger (DYC11) and convertthe measurements to the custom sizes as shown.

TipsTip 1 The scallop template has nothing to do with seam

allowance. The user needs to add the seamallowance. For example, a treatment with multipleidentical scallops at the bottom has a long pointof 18" and a short point of 13". Each scallop heightshould be 5". If the seam allowance is 1/2", adjustthe long point to 181/2" and the short point to 131/2".No adjustments need to be made to the scallopheight or width.

Tip 2 To sew a scallop design, draw or trace the scallopdesign on the fabric; do not cut; sew first; then cutthe design. This way there is less chance fordistortion.
