Can I use a circular needle instead of double pointed needles?

[malkikate]

Hi everyone!

I'm trying to make a beret using a pattern from Twinkle's Weekend Knits. The pattern calls for size 19 double pointed needles, but I couldn't find any, so I bought a size 19 circular needle with a 29" cord. It says to cast on 36 stitches. I was wondering if this will work or if the circular needle is too big for this project?

Thanks!
