Scrapbooking is today's equivalent of the photo album. Only instead of a boring plain album that you slot pictures in, the artist in you tries to capture the beauty and spirit of the moment with space for journaling if you want. It can be a book or just 1 sheet to pin on your notice board or frame up for the wall. Also makes a nice gift for friends and family.
You can buy scrapbooking supplies everywhere. Specialty shops like Papermarket obviously carry more supplies, conventional craft stores like Spotlight and even stationery shops like Popular have items you can buy for your scrapbooking.
Some onlines Singapore resources if you are too tired to make it out to the stores:
