This is something I tried today and it worked. I wanted straight lines on a card embossed and what I did was take sticky tape (Score Tape, Red backed tape) I took put in where I wanted it and took the top cover off added the embossing powder heated it and it worked. I love it you have to try it. Tip: cover what you have already embossed and be careful when removing the paper what you have already done could smear. I know I did it. Here is my sample so far the card is not finished but the Melon Mambo and the Tangerine Tango strips are embossed. I used Wild Wasabi to emboss the ice cream.
