Please, note that there is NO written pattern provided

• Metal hoop 19 inches or 48 cm in diameter.
• 1/2 lb (227 grams) of 10/2 Linen Yarn, 100% Unbleached Linen (1500 yards/1 lb).
• Crochet hook, 1.75 mm
• Double sided tape 6 mm wide if the hoop is to be wrapped with yarn

The entire pattern is done with two basic crochets: chain and treble, using 1.75 mm hook.

The pattern will work for other yarn or hook size, but the diameter of finished product will most likely be different, and a smaller or larger hoop may be needed.
Stiffer yarns are preferable. Softer yarns give more stretch.
