I am still getting together the various tools and gadgets but hopefully the few things I have learnt I need to have as my essential kit will help you when you start getting into the hobby.
One really important thing to add here is that you do not need a lot of kit to get started with this hobby. There are plenty of great products out there to try that it is sometimes really easy to forget about the most basic parts of your kit that will make card making a lot easier.
Scissors - whether you are left handed or right handed get a good pair of larger scissors and if you are planning to cut out a lot of small elements for your cards I certainly would recommend getting a small detail pair of scissors too. When I first started I thought I would be able to get away with just one pair of large scissors but I found it quite hard to cut out smaller elements.
Cutting Board - you have probably seen from my pictures of my cards that my cutting board gets a lot of use! The one I have is a self healing board and I use it for cutting, gluing and stamping - basically it gets a lot of wear and tear. It is quite handy to have one that has the various dimensions and rulers running horizontally and vertically as if you are doing small detail cutting out using a scalpel then these act as a good guide.
Scalpel - at first I was petrified of using a scalpel as it brought back memories of dissecting various objects for science lessons but once I got used to the pressure I needed to use the Scalpel and got my confidence up it seemed a lot easier to use than I remembered.
Glue, Glue strips and tape - I have several tools for gluing including a multipurpose tube of glue, square foam pads/strips and double sided tape rolls. I didn't spend a fortune on the glues but I did buy ones suitable for paper crafting. It is worth buying a glue specific for the job but with a bit of searching around the internet I did find it more cost effective to buy in bulk once I knew which ones I preferred.
Stamp Block - I have two sizes of stamp blocks. One for smaller stamps and a larger one for using with larger rubber stamps. Both are clear and have sizing lines on them to make it easier to be a bit more accurate. These are great for starting out with stamps and help get the confidence that you are stamping straight on your card.
Wet Wipes - these have been a vital part of my kit, from cleaning up ink on my work surface, cleaning off stamps and generally keeping my work surface clean and free from unwanted marks on cards. I will always keep a pack close to hand when I am working on a project.
Card Stock - I started simply with some blank card stock to get going. I did make the mistake of using quite a flimsy stock to start with but now I try and get 300 gsm card stock simply because it is strong enough to take papers and embellishments. I still keep the lighter stock as these can be useful if you are sending cards in the post but want to keep postal costs down. By keeping the card simple and without using too many additional embellishments I found that the lighter stock did its job but out of choice I like the feel and finish of 300 gsm.
As I add to my collection I will let you know what new tools and tricks I have found but I hope the above helps with getting you started with your hobby.
Before I forget it is worth having a look at auction sites as people regularly upgrade their tools etc and there can be some great bundles of craft clear outs that can help you get started too.
