Try contacting the pattern company. Otherwise, you will most likely need to purchase a duplicate pattern to get the instructions.

It looks like you may fold the fabric (wrong-sides together) on the center line, stitch the raw edges together but leave about a 3-4" gap unstitched (somewhere around the middle), then turn the fabric right side out through the gap, push out the points on the corners, hand-stitch the gap closed, then press.

There are many Bucilla Cat Cross Stitches available. Here is one of the web sites:

Have you installed the stitch selector pattern module for the patterns you want, seated it properly as outlined on page 52 of the instruction book following all 7 steps? (Page 54 identifies the knobs and lever's that need to be moved to successfully install the pattern module)

If that is done correctly, then selecting a stitch is done with the stitch selector lever being moved under the letter corresponding to the stitch you are trying to select. (Shown beginning page 55) You also need to move the stitch length knob as indicated.

You will need to be sure you are following the instructions very carefully as there are a number of settings that need to be made to ensure you get the stitch you are trying to achieve.

I hope this helps you.

First of all try a guage/tension swatch. Cast on 25 stitches, use 5,5 mm needles and knit stocking stitch for 4 ins. This should tell you if the pattern will work with these needles and yarn.
Count your stitches over the 4 ins and see wht you have to the inch. This is your guage oe=r tension then check with your pattern to see what the guage/tension is.
To change a pattern this drastically needs an experienced knitter
If it is the pattern only that you want. then find a pattern for 8 ply and use the stitch count on the original pattern and modify for the new pattern.I wish you luck.

Use a separate fabric and stitch it on to the reverse side and into the existing border stitching for a nice seam. For a bib I would suggest something plastic like to stop fluid from seeping through. Your local fabric store should have some inexpensive plastic fabric for this.

When you select a pattern does the needle move back and forth? do you make sure the stitch width lever is on straight stitch then select your pattern then select the widest stitch width? if when you select a zig zag stitch the needle does not move from side to side then you need to look in the top at the finger that goes round the cam.

Several things may be causing this.

First, make sure that the wire rack is DIRECTLY above the cones of thread (it may be backward). The thread must come straight up from the cone as it pulls off. Not coming straight up will cause a wavy stitch because of the thread dragging on one side of the cone.

Make sure that the threads are fully pulled into the tensioners, not riding on top of the discs.

Inspect the needle plate and ensure that the stitch forming pins and or fingers are intact.

The question was regarding the Elna 2002 not 2007 and it wasn't a problem. I just do not understand how the pattern selection works. Thank you.
