In this project we'll be using all-purpose spray adhesive, to transform a dingey figurine from the past into modern decor. A quick coat of paint and spray adhesive makes this project perfect for the weekend or weekday evening.

The value from this formula is resolution. According to this equation, the larger the numerical aperture (N.A.), the smaller the radius of the Airy disk. Therefore, a lens with a larger N.A. will be able to resolve smaller features, resulting in a sharper image.

To avoid the flocking dust from sticking in awkward clumps, the mini strainer works like a flour sifter to distribute the flocking powder evenly across the surface of the figurine. Shake out a little bit at a time, and gently turn the figurine to coat the surface in velvety powder.

Repeat until the figurine is flocked to your heart's content. Some figurines I've made needed just one coat, others needed two to three.

Start by painting the figurine with acrylic paint. Depending on the surface material you are painting, you may need multiple coats of paint. Acrylic paint bonds really well to most surfaces, but especially clothes, so be sure to wear an apron or things you don't care too much about, just in case. Give the paint a full day to cure.

Numerical aperture, or N.A., is a value that indicates the resolving power of a lens and is defined by the equation below.

Spray glue is awesome because it dries so quickly and can be substituted for white glue, hot glue, tape, and other adhesives, just be sure that the adhesive you are using can be bonded to your project materials. Spray glue tacks quickly and forms strong bonds in very little time. Because you are spritzing a high-tack adhesive onto a surface, it has very little surface penetration. This characteristic makes it ideal for forming bonds with everything from paper, cardboard, fabric, and foam to plastic, metal, wood and much more. Some are fabric specific, rubber specific, or even temporary.

Although N.A. determines the resolution of a lens, diffraction also plays a role in what can be resolved. Diffraction is a phenomenon that causes light to spread out like a wave. This property prevents even the most high-resolution lens from being able to gather focus to a single point source, making the focal point more of a disk. The smallest-size light disk that can be resolved is known as an Airy disk, and its radius is expressed by the formula below.

To prevent overspray going all over the place, it is smart to place the figurine in a box. I like to wear gloves while handling and moving pieces coated in spray adhesive, once it coats skin it can be really tricky to handle the project.

This can work with any figurine, or really anything I suppose, so use your imagination. I found this particular figurine in a box of things my mom had given me a few years ago - I had painted the dog at one of those Glaze-your-own ceramic shops in 1997, I was 10. It didn't really work in my current apartment, but I thought it would be fun to dress up this piece of history and turn it into a keepsake I still want to hold on to.

Remember those tacky velvet statues from the 60s and 70s? Well, they weren't technically velvet, they were flocked! (And in my opinion, tacky in the best way :D) Flocking refers to the process of depositing teeny tiny fibers on to a surface to create smooth matte texture.

Let cure overnight and voila! I turned a relic from my personal history into some 60s inspired throwback decor. This technique works great with glitter too, but I recommend spraying a few coats of clear coat after you apply glitter to a surface with spray adhesive. This will prevent it flaking off when it comes into contact with other surfaces.

The spray adhesive you choose will specify how long it remains tacky for, in this case, the adhesive I was using would remain sticky for 30 minutes before it began to cure. The flocking dust is a little tricky to get into all the nooks and crannies of figurines, so the period of the cure time is actually very helpful.

n: refractive index of observation medium [e.g. n(air) = 1]θ: angle between the optical axis and the light at the outermost of the effective diameter of the lens
