Chenille Yarn

I am sooooo frustrated. I tried (about 3 times frogging) to knit a simple washcloth from chenille yarn. Sometimes I tend to knit a little too tight, so I was careful to keep it fairly loose. The pattern called for yarn overs to increase and then knit two togethers to decrease. When I got to the K2Tog, I had the hardest time getting the needle into the 2 stitches (they seemed so tight) and I would always drop one of the stitches before it made it onto the working needle.

I am a newbie and have knitted a scarf before and this washcloth was a very easy pattern. I just can't get the K2tog right ----- I don't know if it was this yarn or chenille harder to knit?

Thanks for any advice you can give me!
