This is one of my creations, its made with No 30 crochet thread - so not the finest by any means. This is the classic Irish rose with rose leaves, its one of the most popular Irish crochet motifs.
A typical & traditional use of Irish crochet is to create garments and garment fragments such as colars or cuffs. Looking through some of the old pattern books I confess that I wouldn't have the patients to create some of the work that they show ... but the detail & workmanship is amazing.
This image is from Priscilla Irish Crochet Book No1, originally published in 1912. I cannot imagine the patients required to create something like this - that's why I stick to smaller pieces like jewellery & motifs.
I am always fearful that I would ruin a well made motif by trying to incorporate it into a larger item ... perhaps as I get more confident with creating Irish crochet I may become more adventurous.
