What is the best type of yarn to use for gloves?
What does your pattern suggest? Do you want gloves for subarctic conditions or chilly days? Thick gloves done in worsted weight are nice, thinner ones done in fingering are also good. It all depends.
There is no one best type. It depends on the pattern and your needs. There are patterns I all weights and fibers of yarn.
My favorite is MadelineTosh yarn for fingerless mitts. I recently knit several pairs using the MadelineTosh Worsted. Love love love it!
MadelineTosh Pashmina Worsted:
Another pair using MadelineTosh Vintage Worsted:
I like the fact that MadelineTosh will use the same color ways across her different weights and fiber formulas. So I made complementary scarves to “go with” the mitts, but using fingering for the scarves.
The yarn isn’t terribly expensive. It blocks beautifully. It feels wonderful next to the skin. I really stand by this yarn, especially for 100-400 yd projects. Larger projects requiring 2-3 hanks such as a shawl will absolutely necessitate alternating the 2-3 hanks every two rows to prevent unsightly color changes where you’d otherwise finish one hank and attach the next. Can’t do that with ‘handpaint’ yarns, as you prolly know.
