Loop stitch questions.....>>>>

Okay, I’'m trying this. The first thing is that the loop on my left thumb is pretty hard to hold on to. Anyone give me any tips for this?

The second question: my loops aren’t realy the same size. Is this because I’m new at this stitch? Do I want them to be about the same?

Thanks in advance!!

I think they should be about the same size, that will probably come with practice as will getting it to stay on your thumb.
