I purchased 3 Sets (size Full) of these sheets. They are, hands downs, the best quality flannel sheets I have ever purchased ... heavy weight, quality construction made to LAST ! 24-inch deep pockets (deepest I have ever found) with wide elastic all-around, remain securely in place at all times. Note: this superbly heavyweight flannel is NOT the ultra soft pajama-type flannel that is not well suited for sheets. However, upon opening the first package on the day of arrival my first impression was negative ..... I was put off by the thickness, initial stiffness, weight (first word that came to mind was denim), the lower fuzz factor and made a knee-jerk decision to return them without giving them a test run. But since I loved the colors and varied patterns, I decided to think about it for a day or two. So, initially, I decided to keep at least one set and return the other two. I then proceeded to wash one set and try them out. Note: I ignored the washing instructions (which seemed counter-intuitive) so I did NOT add vinegar or fabric softener. I washed them in WARM water (cold rinse). Set drier on LOW and since they are so heavy and thick I added 2 fabric softener sheets. One night on these sheets and I was SOLD ....... sturdy, comfy, warm and plenty soft enough. DECIDED TO KEEP ALL 3 SETS. Another delightful PLUS - - I did not have to settle for cheaply made, inferior quality flannel sheets in BORING solid, pastel colors. Each set is a different color/plaid/pattern. LOVE THESE TOP QUALITY SHEETS. So very glad I decided to give them a fair trial. HIGHLY RECOMMEND !
