Archival Methods 4-Ply Bright White 100% Cotton Museum Board contains 25 boards that measure 16 x 20" each. The board is a high-quality mat board used for many fine print and document projects. Whether for traditional print or digital technology, this board will provide a solid, acid-free backing that is perfect for display purposes. It can also be used for small mat cutting where, for example, a 2-ply board will provide a 1/32" separation between the work and the glazing.  

Your best print deserves the best mount possible. Presentation is half the battle and Archival Methods gives you the way to show off your best work. This is quality board designed for archival display.

For window mats and mat backing, Archival Methods recommends a thickness of 4-Ply, which creates a 1/16" separation between artwork and glazing and provides a flat, supportive backing.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

Best no-show socks ever!
Size: 6-10, Color: Black
If you're tired of wearing socks that slip off and show in your sneakers, then you need to try these amazing socks! They are designed to stay in place, even after being active all day. They are incredibly soft and comfortable, and they are truly no-show, so you won't see them at all. I've been using these socks for years and have never had any issues. In fact, I love them so much that I've bought multiple packs, and my family members have started using them too. Don't waste any more time with those annoying socks that slip off and show - give these a try and you won't be disappointed!

The best
Size: 9-11, Color: Black
Seriously the best non slip low cut socks you can find. They stay in place all day and I love the fabric. They are thin which I prefer. These are really the only socks I wear.

Great socks for the price!
Size: 6-10, Color: Black, Size: 6-10, Color: Black
I love these socks, they are perfect no shows but the material is thick enough for toes not too go thru. The grip is perfect and keeps the sock in place all day. I would definitely order true to size as the fit was perfect. I was surprised to find these socks at the price I did, especially when I got the socks in both black and white.
