A: You can. The result will be very bold strokes that will be difficult to blend out. If your intention is to blend the color out evenly, wait until the paper is completely dry to apply the pencil.

A: I usually leave them blank inside when I make them. Sometimes I'll even leave a sentiment off the front. That way when I need a card, I can customize it to the recipient and the occasion. If I have a sentiment that's appropriate for the inside I'll add it when it's ready to send.

A: Instead of buying embellishments like enamel dots or rhinestones in every color, look for white or clear ones. These can be colored with alcohol markers to match your project.

A: Some dye inks are formulated to dry slowly, for blending and water-reactive effects. You can help the process along with a quick heat set. I always seem to warp cardstock with a heat gun despite my best efforts, so I'd recommend setting with an iron. Lay a paper towel or parchment paper over the cardstock, and then run a hot, dry iron over it for 30 seconds or so.

A: You'll definitely want to use a water-based product for your first layer of color - oil and alcohol based mediums will not work. It will need to be a medium that will still react and lift with water once dry, so your best strategy will be making some swatches to test that property. Best results will be with reactive dye inks, which are formulated to lift and react with water. Some watercolor paints will lift, and others are formulated to stain and will not lift as readily. Craft and acrylic paints are water based, but probably won't lift after they've dried. Paper choice will make a difference too - some papers will readily absorb the ink, and others will allow it to sit on the surface.
