I have been using Staples Card Stock to make personalized calendars for 13 years. I make 10+ calendars every year and give them as Christmas gifts. My first year I used photo grade paper and it was hard to write on. Normal paper isn't thick enough to print a full size photo on one side & calendar grid on the other. The image would show through and it's flimsy. Card stock is the perfect medium. It's great for photos easy to write on sturdy and affordable (unlike photo paper).
I use this card stock for making my own birthday Christmas and other special occasion greeting cards. It's a good sturdy thickness folds nicely and is suitable for various mediums my favorite being fine and ultra fine multi colored Sharpies. My family and friends always seem to get a kick out of my home made cards.
I use card stock on a regular basis for postcard mailings. It works beautifully in the printer has a professional appearance and holds up well. How do I know it holds up so well? Because the post office returns numerous cards to me as "undeliverable" and even going through three postal systems the cards still look fresh.
I am a crafter and I love the staples card stock. It is a good quality product for a great affordable price. I use for all kinds of crafting projects from card making to scrapbookking to poster making. It cuts well and the ink doesn't bleed through. I also use it in my printer for projects as well. For tent cards and place cards. It does't jam the printer. Watch for sales and use your coupons! Then it even more of a great bargain. I would defintely recommend this product to any crafter.
