1 Introduction

Although I don't really plan to investigate working at stitch level, it turned out that even simple vector-based and auto-digitized designs do gain from making changes at this very low level.

  • none so far ....
Part of a QR tag

Two examples I encountered:

  • In my first one-day SEU class (oct. 2011), someone wanted to create a fairly small QR tag. Digitizing is easy, since QR code only has one color (black) and clean lines. However, there are many jump stitches and instead of removing all these, you'd rather have them pass through the corners of the rectangles. Of course, a few will remain as you can see in the simulated picture below.
  • Eyes are always a problem. Small circles are not auto-digitized or turn our to be rather slim and ugly ZigZags. One solution is to make these bigger, an other is to add stitches manually and/or move them.

2 Moving a stitch

In order to enter stitch editing mode:

  • Hit F12 (or select Edit Stitches in the upper left Designs panel
  • Hit F11 to exit from this mode (or some other magic command)
The Stitch Edit tool / mode

You now can drag stitches (hold down the mouse and do it). By default, only one point will move.

Moving a stitch and keeping the rest in place

If you untick Keep in place then the whole group of stitches after the arrow will move. Try it to see :)

Btw. the QR code was embroidered and was recognized with a cell phone app.

3 Inserting a stitch

  • Select a stitch somewhere
  • You now can insert a stitch somewhere
  • The "arrowed" stitch and the stitch after it will be connected
  • In the left-most panel, select insert Insert
  • Then click somewhere. Each click will insert a new stitch
  • Hit ESC once you are done.

Let's see have a look at an example.

(1) Initial digitizing

In principle you should know how to digitize a vector image, but we repeat the procedures explained in Stitch Era - simple digitizing and Stitch Era - digitizing complex vector images.

The following picture is a cartoon ladybug found at OpenClipArt.org. Its eyes are made of three circles and difficult to auto-digitize.

Let's what auto-digitizing does:

  • Open the SVG in either Illustrator (preferably) or Corel. If you don't own either one you can try importing via Inkscape or else vectorize the PNG picture...
  • Import the SVG opened in Illustrator to Stitch Era with Artwork->Get from Application
  • Since the eyes are made of four layers (black head, white eye balls, black pupils and white pupil part) we should simplify. We do it the easy way:
    • Select all (CTRL-A)
    • Combine Vectors -> Simplify. This operation will punch all the objects on top through the objects underneath, i.e. we we will wind up with a simple flat structure

  • We then further simplify the drawing by removing the vector borders.
    • In the Object manager, select all the vectors that have borders and make them fills only (in the format panel on top, click on the Vectors Only Body rectangle)
  • We then closed the holes in the black pupils since we would like to stitch the little white circles on top of the black pupils
    • Move the little white circles out
    • Select each black pupil and in the Reshape panel, click Remove holes.
    • Move the white circles back
  • Finally, combine the 2 parts of the mouth (Combine->Addition)
  • For easy of stitching, move all the black vectors up and you should have something like this:
Flattened borderless ladybug vector art
  • Select all
  • Convert->To Embroidery
  • Select Art to Stitch (Intelligent) ... using default parameters
  • If needed, adjust stitching order by dragging stitch sections up or down. I print red first, then black, then white.

The planned stitches will look like this (I provisionally made all the white stitches violet, since you can't see white on white...)

Auto-digitized ladybug

From my small experience I already can identify several issues. For example, our lazy "flatten" the whole vector art may not be ideal. E.g. when areas touch each other, there will be many stitches on a border and that will make the embroidery a bit too stiff (it's usually better to have some overlap). We also could change the ZigZag of the black pupil to some radial structure.

However, in this example we are only concerned by the small white circle on top of the pupils and the mouth. Both may come out a bit too small. One solution would be to change the vector art, e.g. make them wider. Another solution to tune directly the stitch section, both shape and some parameters. Instead we will play with stitches here.

(2) Adding Stitches

  • Zoom in as much as you can (i.e. 2500 %)
  • Tick all the buttons in the button left panel (show sections, markers, connections, etc.)
  • Hit F12 (or select Edit Stitches in design panel, left/up of workspace) to enter the Stitch Edit tool
  • Select at stitch, then move with LEFT/RIGHT arrows until you find yourself at the beginning (somewhere on top). The select node comes after the black arrow (showing the incoming thread).
First/start node selected
  • Select Insert in the top left Stitches & Jumps ribbon panel.
  • Now add stitches. I added an outline plus two stitches within the circle. Select "Move" again once you are done or directly hit F11 to exit from the stitch edit tool.
Stitches added
  • Make the color white again and regenerate the stitches.

Ain't she got a lovely right eye ?

Of course, we now should stitch this for real and then decide if our design is better. Maybe later, but I hope that you understood how to insert stitches with the stitch edit tool.
