I am making a dress that calls for Vilene bias tape to reinforce neckline and armholes (it's sleevless). I've never used that thing, so there I go to the nearest fabric shop, which has quite an amount of haberdashery, and ask for it. They point me to the ordinary bias tape. "No, I want Vilene bias tape", I say. "It's iron-on." They didn't have it, so I settled for the ordinary one, which at least came in the same colour as the fabric I am using. I paid for the stuff I bought and... the shop keeper said: "You won't find iron-on bias tape, they don't make that".
Well, that's it. I am never, ever going to buy anything else in that particular shop. I really HATE when they tell me in a shop that something doesn't exist simply because they don't have it in stock. It absolutely makes me want to slap them.
But I don't have time to order it on-line, so I looked for an alternative solution, and I found one in another forum: someone used ordinary bias tape, cutting it to size (the fantom tape made by Vilene and that you can find fairly easily on-line is just 12mm wide), sprayed it with temporary adhesive and put it in place, sewing then a line 1/4" from the raw edge, which also stabilizes the bias tape.
That's a fantastic idea, and sewing the results in the pics she posted I must say it gives great results. But I can't find temporary adhesive anywhere -again the same problem... But oh! I've got something else! I've got hemming tape, which is a very thin web that becomes adhesive when you iron it on - on both sides. It's spun out of the adhesive stuff, so it's thinner than paper. So I've prepared the bias tape, put it on the hemming tape, put both on the fabric and ironed (putting a towel on top so that the hemming tape showing from under the bias tape wouldn't ruin the iron sole). Then did the stitching. Done!
