It is being blocked and the sparkle is water droplets not sparkle yarn. I used Knit Picks Andean Silk in hyacinth as my dd has a skin disease and has problems with very much wool in her sweaters and can’t wear acryllics at all. I still have to get the organza ribbon and sew it to the front and sides to wrap it. I have decided to sew snaps on the ribbon and sweater so the ribbon can be removed for washing or if she would like to change out ribbons she can easily do that too this way.
Nice sweater. Too bad about your daughter and her touble with wool and acrylic. It’s good that there are a lot of yarn choices these days so you have something left you can knit with. This turned out very nicely.
