A: It can! After you've attached two tabs, you can tuck a treat inside before adhering the last side - you might even want to add a little 'pull' tag to the adhesive on one of those last tabs. Unfortunately since it needs strong adhesive to keep it closed and hold the extra weight, it can't be used as an ornament after it's been opened.

A: If you have a stamp positioner, this technique is very easy! Start with your lightest color and ink the stamp up randomly. You can soften the edges of your inked areas with a baby wipe. Stamp, wipe the ink from your stamp, and repeat with your next ink color(s). You can also apply the ink with a dauber. This tutorial might give you some ideas. Another option is to create a multicolored ink "pad" with drops of ink on a baby wipe - that tutorial is HERE!

A: You can overheat the powder, and it will go dull and sort of soak into the paper. If there was powder rubbing off, then it probably wasn't heated long enough. Paper can make a difference though too - some papers that are more absorbent may take in the ink before the powder has a chance to stick. 

A: I'd definitely create a card that's tactile with lots of raised elements - die cuts, embossed layers, embellishments - with a variety of textures and recognizable shapes. For the sentiment, there are braille fonts that can be downloaded for free - I would print the sentiment in reverse, lay the cardstock onto a firm foam sheet, and press into the dots from the back side of the cardstock with a small stylus. That way they'll be legible from the front.

A: A quick search showed several card designs with a slightly bowed front - this is done by creating a front panel just slightly wider than the base, and adhering it only at the sides. Check out the Bendi Frame Card tutorial for step-by-step instructions!
