Entrelac looks challenging but is not as at all difficult once you get the idea. If you have never done it, my suggestion would be to search You Tube “entrelac” and watch a couple of videos. You will soon see how easy it really is and be ready to knit this lovely sweater for your doll.
This sweater can be done in two colors or in one color. The purple and yellow version uses seed stitch for the rest of the sweater while the apricot single color sweater is worked in stockinette.
