How to unpack, store, flatten, adjust, and hang your artwork
This canvas is sensitive to the shape that it's been in for the last 24 hours. Curves flatten out easily but creases don't, so I recommend storing it rolled up instead of folded over until you hang it. This is a matte (non-gloss) waterproof canvas so if your hands are oily, it will leave that oil on the canvas. I suggest washing and drying your hands before handling and hanging the piece. The easiest method is to use heavy-duty velcro poster strips, and is the one explained in this article. Make sure to get the poster velcro with teeth, not just the adhesive kind (pictured below). They come in black or white, and you'll need 2 sets of them..
This step gets rid of the slight curl that happens at the edge of the canvas after being rolled up. Pictured below is an example of how the edges look if you don't flatten your artwork for 24 hours before hanging it. If that slight curl doesn't bother you, skip to Step Two. Lie the poster poster on a hard, flat surface--facing up so you don't get the artwork surface dirty. Cover the artwork with a towel to prevent damage, then put books on the corners and edges to weigh the corners down. Edges and corners will lie flat after 24 hours.
Inside the poster velcro package, there is an alcohol wipe. Use it to wipe down the wall surface where you will put the poster velcro. Lie your artwork face down on a clean towel. Tear the velcros strips apart along the perforated lines. You should have two packages of two, so you will need to tear apart four sets, into 8 pieces. Stick the velcro faces together (velcro hair to velcro hair), making sure to press them fully together until there is no more clicking. You now have four sets.
Remove the paper backing of one velcro set and stick it to one of the corners of your artwork, referencing placement and direction in the picture below. You want to put the flat sides of the velcro as close as possible to each edge of your artwork because the closer the velcro is to the edge, the less curl there will be when it's on the wall. The velcro strips should be horizontal instead of vertical, because it prevents sagging in the middle better than if the strips were vertical.
NOTE: You are only removing ONE side of the paper backing for each velcro set, in order to attach it to the artwork.
Finish attaching the other 3 Velcro sets to the artwork.
Remove the paper-backing from the top two corner Velcro sets. Leave the paper-backing on the bottom two corners. Holding the two corners away from each other (pulling the poster tight), stick the top 2 corners to the wall as level (horizontal) as possible.
Here’s the beautiful thing about this kind of poster velcro; if you realize that you’ve hung it slightly crooked, you can separate the velcro teeth at one corner and slightly move that corner up or down, then press the velcro back together. BE GENTLE with the poster velcro each time you separate it, and when you are pressing it back together, don’t use the tip of your finger. Use the flat of your palm or a scrunched up washcloth, so you don't leave creases in the canvas.
Once the top edge of the artwork looks even to you, remove the paper from one bottom corner. Then, being careful not to let the sticky back of the third corner touch the wall, take the paper off the last corner. Pulling these bottom 2 corners down and outward (pulling poster tight), stick them to the wall.
As one final touch, you can separate the poster velcro teeth at one of the bottom corners, then pull the corner tighter before pressing the velcro back together. This will take out any remaining slack in the canvas.
Over time, the artwork may sag some as the canvas sets but whenever that happens, the poster velcro teeth can simply be separated, the slack pulled out, and then the corners re-attached!
