Crochet yarn and hook: I used 100% cotton sport yarn in 5 colors (terracotta {150gr}, mustard {40 gr}, sunny yellow {20 gr}, brown and off-white {15 gr each}) metal 3 mm hook (UK11) (US 10/3).
The granny stripe pattern is used to make this top.
Used terms in American terminology: chain (ch), slip stitch (sl st.), single crochet (sc), half double crochet (hdc), double crochet (dc), dc2tog, 3-ch picot
Other: 4 buttons, sewing needle and thread, tapestry needle. The tutorial shows how to make crochet covered buttons (buttons size 2mm).
Length of finished top buttoned up: 39 cm (15.3”) across and 26 cm (10.2”) down. Fit size: S/M.
The top can be made in one color only, for which you will need about 240-250 grams of yarn depending on whether you crochet more loosely or tensely. Leftover yarn is great for this project.
