Hope all is well!
I'm going to show how I stretched my stamps with a little masking. I used the bunny and chick from my Spring stamp set to create a Christmas card by adding the snowman's hat (from my Warm Wishes) stamp set and drawing a hat on the chick.
For the chick I took some washi tape (post-it's are great for this too...I usually use post-it but ran out of them) and cover the top of the chick's head where I want to draw the hat. Draw the hat with a pencil first than trace over it with a marker and erase the pencil.
Ink up the stamp, remove the washi tape and stamp.
I did the same with the rabbit.
I too the snowman stamp from my Warm Wishes stamp set and masked off everything but the hat, after I inked the hat and took off the washi tape I rubbed off the ink where I wanted the ears to be with a baby wipe.
Don't worry if it doesn't look perfect...once you colour it those little mistakes won't show. Also you can fix any lines (if they didn't stamp clear) with a marker (I use Sakura Pigma Micron) and use a white gel pen to erase any tiny mistakes.
Again, same thing with the ears....
I embossed polka dots on the vellum to create the snow...I adhered the sides of the vellum at the back so the glue doesn't show through at the front.
I coloured my images with Graph'it markers and as you can see any tiny imperfections are gone once coloured in.
Have a great day!
