Blanket dress, no pattern

The blanket dress was (and still is) made by sewing two lengths of woven rug together, which is why it's sometimes called a rug dress.  It's a traditional garment for many tribes, though I'm only familiar with the Navajo version.  I'm not Navajo, but my husband is.  My sister in law was here a few weeks ago, and we went shopping to get material to make her a pseudo blanket dress.  Genuine Navajo rugs are exquisite and expensive works of art, and not something I'd want to screw up in any way, a distinct possibility since this was my first time making a dress like this.  So we went for something reminiscent of a rug pattern.  She wanted something to wear for various events but it didn't have to be authentic, which is good because she would have to have someone other than her Italian-Irish-German-English-European mutt sister in law to make it. You know, like a Navajo seamstress.

I apparently didn't take a picture of the raw materials as I usually do, so you'll have to take my word for it when I tell you I got three yards of a knit fabric, rayon acetate for lining and thread.  I think it all came to $30.  There is no pattern, because it basically consists of sewing two rectangles together.  I interlined the knit with the rayon acetate, even though knits usually aren't treated that way. However this knit had minimal stretch and I wanted to give it more weight and body so it would hang the same way a genuine blanket dress does. It also served to create facing for the armscyes and neck. Start to finish it took about four hours.  I started it at 10 PM the night before sister in law was leaving to go back home and finished it up at 3 AM.  I'm getting too old to stay up that late anymore.  But when she woke up, she had this waiting for her:

Sister in law has a traditional woven belt to wear with it, but I don't happen to have one so I used my husband's scarf instead.  Lilly the Calico was a bit miffed there were no pattern pieces to lay on with this project, but she did seem interested in the scarf tassels.

I just got fabric to make a similar dress for my mom. I'll post pictures of it after it's done and I've sent it to her, because I want her to be surprised!
