I want to make an infant-sized version of this hat (PDF).
The current pattern (assuming correct gauge) makes a hat with an 18.5" (47cm) circumference. It seems that a common size for a newborn/infant hat is around 12.5" (32cm), which is about 1/3 smaller.
The pattern calls for using a 6.5 mm crochet hook but I'd like to use the same size hook that I'm already using (for the blanket) which is a 5 mm hook. To make this slightly more confusing, the "materials" section calls for a 6.5 mm hook but the "gauge" section calls for 6 mm, so I'm not sure which of the two is actually correct.
The pattern gauge is:
13 stitches and 11 rows = 4" (10 cm) with a 6 mm hook
The yarn I'm using has the following factory gauge info:
18 stitches = 4" (10 cm) with a 5 mm hook
Given this info (and assuming I crochet perfectly on gauge), do I actually need to adjust the pattern at all or is the hook size/yarn difference sufficient to make it small enough?
If I do need to adjust the pattern, the following info may be useful:
- The hat is worked in rounds from the brim to the top.
- Each of the first 19 rounds consists of 50 stitches, grouped in 5s, so 10 repeats.
The decrease rows are where my main concerns lie. It's simple to reduce the main rounds by 5 or 10 or 15 stitches to make the circumference smaller but I'm not sure how this will affect the decreases at the top of the hat.
For balance, it seems like I may also need to reduce the number of rounds but, again, this may depend on whether the hook change is sufficient to reduce the size or not.
