I’ve made some small hairpin lace, the strips were only 1 cm wide. The off-white lace is made of a size 12 thread, the size is 2½ x 17 cm or 1 x 6½ inch. The green lace is made of a new thread I bought recently, DMC Cébélia. I used a size 1 crochet hook for both.
The strip for this hairpin lace was 2 cm wide. The finished rickrack lace is 5 x 35 cm or 2 x 13½ inch. The thread is mercerized knitting cotton. I used a size 2 crochet hook for this one.
