In Uruguay, we call hot dogs “panchos” :)
You should crochet a set of panchos for yourself! The pattern also includes instructions on the ketchup & mustard bottles.
Oli (5 already!) & Martina (1) are having lots of fun playing with these, and I hope whoever you make them for will love them too :)

The hot dog itself ends up being approx. 6.5 inches/16 cm, the ketchup bottle approx. 4.5 inches/11.5 cm tall, and the mustard approx. 3.5 inches/9 cm tall. Depending on how tightly you crochet and the type of yarn you use they might be a little bit bigger or a little big smaller.
