I have centred all the cards today using Vellum.
Here is a brief description of the sizes and techniques involved.
This card uses a neat way to attach Vellum. Cut a strip that measures the mat piece, then add an extra 1" to the length. The extra 1/2" inch on each end will wrap around and be secured behind the mat piece. Emboss the images and colour with Blends from behind.Vellum Overlay Card
This card uses a very different technique of using the Vellum as the card base. You need to be careful when scoring so as not to tear the vellum, so score gently. The card base is standard 8 1/2" x 5 1/2" and the inside mini card is 9 1/2" x 3 1/2" (scored at 4 3/4" on the long side). An extra piece of cardstock is attached to the back of the Vellum 3 1/2" x 4 3/4" to hide the tape from attaching the mini card to the inside of the Vellum Overlay. The floral image on the front is heat embossed on a separate piece of Vellum and attached.
Recessed Panel Card
The recessed panel is an beautiful technique for any pattern paper or stamped images. To create the panel, trim the Vellum to the same size as your mat piece, white heat emboss your images and colour from behind with a blending brush and inkpads. It will be wet for a little bit so set aside to complete dry. The panel used in this card is 5 1/2" x 4 1/4" and the trimmed diagonal piece was trimmed at 4 1/2" x 2 1/2" and trimmed diagonally. Add 1/8" or 1/4" to a coordinating colour and trim diagonally to create the mat panel.
This is the most simple and yet very effected way to use vellum. Choose a dark colour and add white heat embossed images. Glue dots are the best way to attach these.
Hope this quick tutorial gives you some ideas and inspiration.
Bye for now
