I have received some tutorial comments and private messages with questions, so I am posting the picture and answers here in my gallery.
1) MAILING IT: Since this card is so deep, I usually just hand deliver it!! Just pick local friends, ha ha. I have mailed them a few times, but of course I do not use a regular envelope or it will get squished. You can use a Medium or Large sized Stampin up Stamp Box (page 235 of current catalog). Or you can also find small boxes at Container Store.com to mail them in. I will often put them into one of those cheapy acrylic 5x7 frames that are about an inch deep, you know? Then instead of it just being a card, it's more like a gift ... just stick it to the frame and put the greeting on the back. Maybe I'll take a pic of a framed one and post it here... in a minute
2) The dimensions of this particular card (the beach-y one) are 5 3/4 wide x 6 tall. I started with a 6" square but I shaved off a little from the sides.
3) The "Beach Sand" at the bottom: I call it my Sandy Glitter mix -- look on my gallery, I use this stuff all the time!! I mixed about 1 Tbsp. of Dazzling Diamonds glitter with about 1 Tbsp. of play-sand from my kids' backyard sandbox!! I apply it like regular glitter, using the 2-way glue pen. You could probably use Crystal Effects too and smear it out a bit.
4) Watercoloring: Then for the watery ocean look, I used Tempting Turq. and my aqua painter. Make a strong line of color at the horizon with the aqua painter, then blend down. I did the same thing with the sand, using creamy caramel ink, but you can't tell because the sandy glitter is covering it up. The Sunshine is the bold circle from Simply Circles set, stamped in Barely Banana ink then rolled the bottom in Summer Sun ink. This cup is sponged with Regal Rose ink at the bottom and faded into Apricot Appeal ink somewhere around the middle.
Oh man!-- lots of details here -- but honest, this card was much easier than it sounds! Try one and I hope you have fun!! Love, Vickie
