Referencing styles of international artists, Sandy has started to create and showcase her own embroidery on Instagram, with a focus on the animals and plants around her. Other than showcasing her art, this, to her, is also her own ecological record.

Sandy would only create embroidery works on species she has seen in person. Not only is it difficult to create colours, a key to making great embroidery, it is also hard to gauge the size and bodily texture of the species based on photographs alone. She goes through stringent steps to make each piece - from personal observations, photography, data collection, sketching, fabric selection, to colour testing and selecting suitable embroidery threads. Sandy mainly uses the technique of "needle painting", which uses threads in various colours to make contrasts of light and dark. Although the embroidery is flat and as smooth as a painting, the final product has a three-dimensional effect. This type of embroidery requires the design to be flat, and to avoid looping threads, it is sometimes necessary to forego certain details of the species. Sandy tries to strike a balance between the two.

Sandy used to include common urban species like Tree Cotton and Frangipani as features in her piece, but realised that many of these urban species are exotic. Since discovering the stories behind a plethora of Hong Kong's native species on Mui Tsz Lam, Sandy has decided to include native species of Hong Kong to promote local ecology in her art.
