Thanks Lisa for posting that blog link. I meant to and forgot.
I don't know how big the original bag is (I PM'ed Mason204, I'll post here when she responds). I can tell you the yarn I'm using is considered "super bulky" though I wouldn't call it that. The pattern calls for a "bulkY" and the red one (pic above) was made with Paton's Shetland Chunky. Also.........it looks like it might take a tad more than 1 skein, I had heard, but had no idea how much more yarn crochet takes than knitting!!!!!!! So make sure you have at least 2 skeins on hand for this.
I'm about halfway done with my bag, here are the measurements I have so far:
Height (through row 12 of pattern): 7.75"
I can't wait to see what color everyone else's is!
I just recently reformatted my PC and haven't synced with my laptop yet, so my pictures are sort of all over the place, so I can't show you my progress, but wanted to show you a picture of the color and yarn I'm using (Yarn Bee's Dreamy Chenille in China Blue - on clearance at Hobby Lobby, BTW, looks like they are discontinuing the color).
This pic is from someone's stash on Ravelry it's more of a teal than a blue:
