 Posted: Wed Feb 09, 2005 9:31 am Post subject: Marking mylar |
 |
|
Anyone have any great ideas for laying non-permanent reference marks down on mylar film? Pencils and usual fabric marking implements don't seem to work. I am laying down straight rows of reference lines for stitching.
I've been using a narrow-point black Sharpie. That leaves a nice mark, but I need to use solvent to remove the marks later. Of course, I've also been leaving the marks where they are, since I stitch over them, but I'd like to find something less permanent than a Sharpie. Any ideas?
TIA |

| Could you put low tack painters tape down, mark on it and remove it as you sew? |

Don't know if it will work on mylar, but Steve carries a disappearing marking pen.
Good winds...Charlie |

Low tack tape (like Grant said) - placed (half of) the width of your presser foot away (to the right) from the original sew line - use it as a sewing guide.

Sewing Mylar????????
I hope you are using a scrim reinforced Mylar....
And some good adhesive under it, as Mylar tears easily once nicked or pierced by something like a sewing machine needle.
You may try a water soluble marking pencil that you can find in the quilting notions. I have some in different colors so one of them shows up against any color of fabric I use.
Or the tape thing, but why not just use the edge of the tape as a guide
Or make your seam allowance the same as HALF the width of one of your presser feet??? Then no marking is required. Just line the edge of the Mylar up with the edge of the presser foot.
Or lay several layers of tape down on the bed of your sewing machine and push the fabric against the bump of tape.
Or try scoring the Mylar with the edge of a credit card or one of those free samples of laminate (Formica) that you get at the local BORG?

BTW the blue painters tape is medium to high tack.
Where shines is that is for long duration masking operations. The adhesive does not transfer off the tape and onto the fabric etc... I LOVE the blue tape because of this, even though it cost more.
A Quote from 3M's web site HERE
Tape, Scotch® Painters' Masking
For trim and woodwork. This tape can be removed cleanly for up to 3 days. It is a medium-high adhesion tape that is ideal for use on previously painted or varnished surfaces such as window, door and wall trim, and for masking cabinets, carpet and vinyl flooring.
There are many different types of Masking tapes available. Look at a House Paint Store, Automotive Paint Store for the best selection or your local BORG for more options.

One other thing to try is a white board marker. I use it on my light table when cutting multiple lengths of material.

Lyle Lundberg makes sails for his RC landsailers from Cobra Mylar.
He uses white board markers and wipes it off with a rag.
I use a blue thin-point Expo-brand pen with good result. |

White board marker! That's the ticket. I've even got some of those here.
Thanks! |

The mylar is scrim reinforced, 3/4 oz. Cobra film. And it's being sewn onto the back side of a panel of polyester sail fabric, not as a sail panel by itself. It is used to reinforce the existing panel and prevent stretch.
The sewing lines are about 3 inches apart and are used to tack the mylar down to the panel. There is no adhesive under the panel. I'm using a long stitch to prevent tearing. No problems to date. |
