Is there an iron on sealer that works on drapes

Not that I know of, could the tape be too old for the adhesive to melt? I'd go to a fabric store and ask a pro.

Hi there, it is such a pain when something does work right. I do not know much about hem tape but I use the washable fabric glue. I use Aleene's ok to wash it glue. Here is a link to check it out.

Hi ~ make sure it is double sided fusion tape. If it is , then it probably has to do with the type of fabric. Also if the fabric is thick you need to keep the iron on it for a longer time. To protect your fabric you can lay a damp pillowcase over it, under the iron. Good luck !

What strength tape did you get? There is an Ultra hold that might work for you. Joann's or another fabric store would handle it. Good luck.

If you could better describe the fabric your drapes are made of & whether or not they have any kind of lining, I could better tell you how to solve your problem & what to use for the type fabric your are working with. Here are a couple tips you might find helpful.

1. If fabric is cotton type & crisp with starch, most of that starch will be on the backside. Scratch it with your fingernail & if starched, you will see it. Wash the fabric in warm water & dry at room temp so as not to shrink it unless you need it perhaps shorter, then in that case, machine dry hot & measure length again. You may or may not still need to shorten them. Iron them back out but don't starch them just yet. Continue reading first.

2. If drapes fabric has a white thermal or rubberized type backing, iron on tape is "not" going to adhere to them no matter what strength you use. They will need to be sewed or use a strong double sided tape such as carpet tape to hold it. Test a small piece & area for hold. I can't guarantee it will hold just way you want it too but this will be more likely to hold. A hot iron hot enough to melt the heat bond will most likely destroy this thermal backing on the fabric.

The strongest holding of these tapes or iron on products is "Ultra Bond". I'm not sure if the Ultra Bond comes in precut strips or not, but I know it can be bought by the roll or by the yard whereby you cut your own strips whatever width &/or length needed & it doesn't matter which direction you cut the strips going. Most fabric centers carry it.

If you wash fabric before hemming, it's usually best to press out wrinkles first, hem with iron on tape, then lastly iron again using the spray sizing or starch so the spray doesn't interfere with the glue bonding to the fabric.

Hope this helps. You are welcome to ask questions if you wish or need.

Lots of good pointers from Gail.

Make sure iron is hot enough, and press, do not iron the tape on, in other words just lift the iron up and set it on the tape. Do not move the iron back and forth. Use dry settings only, no steam. The steam will loosen the glue.

If your iron is not heavy enough there might not be enough force to 'set' the glue. If not, then try pushing down on your iron when it is sitting on the tape. How much does your iron weigh? Some higher end models such as Rowenta, can easily be over three pounds each.
