Setup notes are plain shorthand for your own records. They are not discount codes. The app itself is a planning tool and has no betting, spin or payout features.

Six tools that earn their place

Nothing here is decoration. Each piece answers a question you would otherwise settle with a calculator and a scrap of paper.

One unit, everywhere

Pick Millimetres or Inches on the order slip. Every cut length, pitch and diameter prints in that unit, and you can flip it later.

A locker that matches your drawer

Tick the widths you really own: 6, 10, 16, 25, 38 or 50 mm. The locker stocks them and the bench offers them first.

A comb you drag

A strip of thin orange ticks sets the pitch. Pull it and watch pleats, fullness and yardage move in the four stat cards.

Nine canon rules, checked for you

The panel reads "All nine read clean" when the plate passes. Example: a 5.0 mm pitch on 25 mm tape sits inside the 5.5 mm that width allows.

Four dials with plus and minus

Rosette diameter across, fullness (times round), centre (part of the plate) and tail rule (times across). Nudge each one and read the result.

A cut list you can work from

Cut order, tape length, pleat count, allowance, tails, centre size, back fastener and totals. Use Open the tape and Mark cut as you go.

How a plate comes together

Settle the order slip

  • Choose Millimetres or Inches.
  • Tick the tape widths you keep. The screens show four ticked out of six.
  • Pick Cockade, Single-tier show rosette or Double-tier show rosette.
  • Tap Open the bench. Nothing is final.

Shape it on the bench

  • Drag the pleat comb to change the pitch.
  • Read pleats, pitch, fullness and yardage in the stat cards.
  • Step the four dials with plus and minus.

Choose tape and backing

  • Tape per tier: Grosgrain, Double-face satin, Single-face satin, Petersham or Watered moire.
  • Widths of 10, 16, 25 or 38 mm.
  • Backing: Pin bar, Safety pin, Buckram disc, Felt back, and a fifth card that looks like Button shell.
  • Press Cut the tier, or Save plate to keep it.

Before the shears

  • Cut the tails first and pleat with what is left.
  • Allow 12 mm at each end of every tier.
  • At this size no tier needs a join.
  • Mark each tier off as it leaves the board.

How the numbers get made

Take the example in the app: a single-tier show rosette, 100 mm across. The rim is about 314 mm. Split it into 63 pleats and each sits 5.0 mm apart. That is the pitch you drag on the comb.

Each pleat eats more tape than the rim it covers. At fullness 2.20 the tape runs to roughly 691 mm. Add 24 mm of allowance, 12 mm at each end, and you land on the 715 mm cut. The app shows that line as "Grosgrain, 25 mm, CUT 715 MM" on the cut list.

The rule panel then checks the plate. A 5.0 mm pitch on 25 mm tape is inside the 5.5 mm the width allows, so the crown will close. The tails are two at 90 mm, each dagged 15 mm deep. The centre is 36 mm, which is 0.36 of the plate. A safety pin gives a covered catch for anything worn all day. The tape total in the example reads 767 mm.
