I am pretty new to crochet and I would like to make blanket pieces like the ones in this picture. Does anyone have any ideas what type of crochet this is (or knitting) and what yarn they are using. I've been searching images and just can't seem to find anything like it. I bought the suitcase and really like the vintage look of the blankets sticking out.

I can't get the photo to appear so here is a link. I really would appreciate someone taking the time to check it out and let me know....it is frustrating. Thanks.
