There are several department stores or malls in Stockholm:
Gallerian, Nk, Pk-huset, Sturegallerain, and Ahlens.
Luckily, they are within 3 blocks of each other in the Norrmalm area on the shopping streets of Drottninggatan, Hamngatan, and Kungsgatan. Of all of them, I liked Ahlens and NK the best for the Scandi-items they offer. The other places had things you could buy anywhere.
At Ahlens, the houeware department is awesome and they carry the Swedish crystal Orrefors and Costa Boda at better exchange rates than I saw elsewhere. Try to time it during the lunch hour, because the cafeteria here is very,very, nice offering the cheapest and best sandwiches in all of Stockholm....like $2.00 us !
NK has a nice bedding department, Scandinavian fabric department, and their rugs are really nice.
I tend to like more unusual shopping, so head down to Gamle Gatan and wander the medieval streets for nice antique shops (prices were high in my opinion) and a few places I'll note below:
Saimi Stalhandske
I love embroidered or cross-stitched linens! Therese offers kits that you can finish at home or offers completed items for you to purchase. There are wall hangings,napkins,placemats,table covers and other linens. Some items feature the dancing Swede's in yellow and blue national costumes while others are floral pieces or fine items with birds sitting on pine branches. Very, Very, nice stuff...but not cheap.
Jobs
Stortanygatan 19. Since 1940, the Job family of textile artists have been busy painting flowers on everything from journal covers to lampshades, to table runners and placemats, to curtains for your windows. Of the seven Job children, 5 are artists. I bought 2 round table covers with a pattern of red and black raspberries among the vines with a finished green edging for $ 195 kr (about $19.50) All the pieces are signed and you will be given washing and care instructions. I really wanted to get some of those curtains....so be sure to be prepared by bringing your measurements with you! I asked if specialty pieces could be ordered, and was told " yes", although I don't know the fees or the turnaround time.
Pasadena
Vasterlunggatan 69. Rita is the Finnish owner of this Scandinavian shop that has the usual sweaters and hats, but the real gems are the Sami items she brings back from the far Northlands. Sami drums,knives,handcrafted birch cups and boxes,and carved walking sticks. Ron bought the most unique coat of black wool (with full lining) with elk suede around the shoulders, collar, pocket edging and cuffs. It is a very handsome thing! You'll have fun looking at these items that are so cuturally diverse from what you know of from your own homeland.
