Many people ask for help in deciding which of the blocking wires to choose: Ultra Fine or Premium. Both types of wires are available in silver, gold, and black in the set of 18. Both are also available in the "super long" set of 6 for reeeaaalllllly long edges or circular shawls, but not in black. So what's the difference between Premium and Ultra Fine? Here is the rundown:
The Ultra Fine wires can be used for scalloped type edges such as on Hemlock Ring, Haruni, or Damask. They are flexible enough to curve this much and more, but don’t “remember” the curve when you’re done; they return to straight. Also, if you’re using cobweb or laceweight yarns, you might appreciate their fine diameter. To do a straight edge will require more pins than with the premium wires (to hold the wire straight) but it absolutely works. Here’s a picture of my Hemlock Ring Doily on Ultra Fine wires:

The Premium wires are just a little sturdier. They can be used for arching curves, such as a neckline or sleeve top, or for a shawl like Swallowtail Shawl, Gail aka Nightsongs, or Annis (from Knitty.com) but wouldn’t work for the “S” type curves as mentioned above. They too return to straight on their own, which is a great feature because your wires are fresh for each project without kinks or bends! Here’s a picture of a scarflet I did on premium wires:

Anyway, I hope this helps demonstrate what is so special about these blocking wires, and if you'd like to purchase a set they are available at my etsy shop inspinknity or my ebay shop.
