Hyperbolic Surface
Skill Level: Easy
Every crocheted hyperbolic piece is different. Rather than a strict pattern, these are guidelines for experimenting and creating your own unique piece.
Hyperbolic pieces can be made with any weight yarn – just pick the appropriate hook size for your yarn. In the video we used worsted weight yarn and an I-9 hook.
Gauge: Not Important.
Abbreviations
ch – chain
hdc – half double crochet
rep – repeat
st - stitch
Decide how often you to want to increase (increasing more often will create a more ruffled piece). In the video we increased in every other stitch, but you could choose to increase in every third stitch, fifth stitch, tenth stitch, nineteenth stitch, etc.
Most crocheted hyperbolic structures start with a relatively small chain, between 10-20 stitches. In the video, we started with a chain of 12 stitches.
Single Crochet or Half Double Crochet (hdc) is recommend for this project to create a sturdier piece. We used hdc in the video.
To make a piece exactly like the one in the video, follow this pattern:
Row 1: Ch 12. Hdc in the 3rd ch from hook. (2 hdc in next ch, hdc in next ch) across.
Row 2: Ch 1, turn. (2 hdc in next st, hdc in next st) across.
Rows 3-10: Rep row 2. Finish off and weave in ends.
You will often find you aren't able to finish your rep at the end of each row. Continue your rep onto the next row: for example, if you are increasing in every 5th st but you only have 2 sts left in the row, work 1 st in each of the next two, ch and turn, work 1 st in each of the next two and then increase in the next st (the 5th st).
