When I was at 'Handmade' last year I overheard a snippet of advice. Apparently, in Auckland, shops ending in 'emporium/ imporium' were great places to get craft supplies. I wasn't aware of any in Wellington, but did note with interest a place called 'Pete's Emporium' in Porirua a couple of months ago. Yesterday we had only the baby at home so we ducked out to explore the shop and to take in Dressmart as well.
I could spend an hour in this store. There was a huge fabric area, with hundreds of buttons (more than Spotlight), rows of trim and all kinds of sewing accessories. There was a huge aisle of birthday party supplies/ stocking fillers and the biggest collection of wigs that I have ever seen. They must stock 100 different styles of wig. It was like a much more interesting version of a $2 shop. They had some fairly decent toys and I got a couple of small things to put in the activity bags I'm assembling for school holiday entertainment. They had a huge selection of costumes and Halloween accessories.
The store is located near Countdown in Porirua. It is massive and kind of hard to miss.
