can somebody advise of some cutters to create a "thicker" style letter in order for them to be able to stand up. Thanks

You can see from the photo that they are on sticks.

Thank You - I had worked out they were on sticks - but was looking for a thicker style cutter to cut the letters out with - as currently only have the thin ones and was looking for some recommendation of cutter. 

They look similar to Jennifers cutters, she's JenniferMI  here on CC. ( and a wonderful decorator).

Wilton also has a mold.  It is purple and has both upper and lower case.  I do use it but it takes much longer than using Tappits.

When I want that look I cut out 2 and glue a toothpick in the middle and stick them together, I then do a border of a different or the same colour going all the way round so that you can't see it's 2. I hope this makes sense.
