I like patterns that are different. Something unique that not everybody has made. I just found one of the greatest. There is under a 100 projects on Ravelry for the Tantric Tank.
This free pattern is really more of formula than a pattern but that is what makes it great. You can use any type of yarn and any gauge. There is no shaping. So it is also a great beginner pattern. Just 2 straight panels and 2 thin ties. Some creative semming. Voila! You are done. I made a couple of small adjustments for my ample-ness (47.5" bust). One adjustment is I made the panels a couple of inches longer. The other is I made it an inch wider. Even with adjustment I only needed about 900 yards of aran cotton yarn. Worked one panel in an Irish Moss Diamond stich and the other in a Seed Diamond stitch.
