Sewing a dress for doll.

Yesterday I spent my time organizing my crafting bagS. I knitted a few pieces on the looms. Last night I started seeing a halter dress for a doll. It was interesting. Just when I got in a rhythm the thread comes off the needle. Three times it happened!  Now this harvest cloth I'm using I got at Joann's Fabric red tag sale.  I got it with the purpose of sewing a dress for a doll. The pictures shown here is the strap for the dress. It has half of the snap on button.  The other half of the button will go on the dress. I'm trying to adjust the dress to fit the doll nicely.
