Pattern repair and preservation are topics that don't come up very often unless you're a die-hard pattern collector or an experienced sewing pattern seller. Many people might reasonably assume that a sewing pattern or envelope with tears is worth less than one without. That makes sense. What they might not know, is that a pattern or envelope that have been repaired with any kind of tape is likely worth LESS than a torn, un-repaired one.
Here is why.
Tape adhesive can degrade and change color over the years. While it might be a temporary repair, old tape can eventually weaken the paper surrounding it, stain the pattern paper, and in some cases eat through delicate tissue leaving nothing but a shredded, inflexible plastic remnant.
I thought that I would put together a quick guide to pattern repair for anyone who is interested. If you have any suggestions gleaned from your own collecting experience, please do leave a comment to share with us!
Allow me to first say though, that this is not a lecture or condemnation to those who have taped their patterns in the past. Your pattern is your property to do with as you wish, and I would simply be happy to teach you a way to help those damaged patterns to not only survive longer, but also retain their value and integrity in the future!
Pattern sellers should pay special attention to how, and if, they choose to repair their sewing patterns. Collectors like myself are not terribly concerned with a torn piece or envelope here or there, but we are VERY concerned with patterns that have been taped in any way. It is always safer to leave a pattern un-repaired and let the buyer fix it themselves if they are so inclined.
The basics:
Do not tape any part of a pattern or envelope with scotch or any other regular tape. Things to avoid using include shipping tape, masking tape, duct tape, washi tape, staples, sewing pins and paper clips. All of these can do more eventual harm than good.
