This pattern has all the alphabet and numbers cut from blocks that are 3.5" wide and 5.5" tall. Having all the characters the same size gives a more uniform look when displayed.
3/4" thick wood will allow the letters to stand on their own but you could also glue them to a base. Paint is another option to add some color.
Amazon has the lowest price in a while on the DeWalt DW788 Scroll Saw. $379
Prices are still fluctuating quite a bit and right now the DeWalt DW788 scroll saw is down to $379. It has been averaging a little over $500 so this is a significant discount. I rate the DeWalt DW788 as a mid-level scroll saw. If you have an entry-level saw and would like to move into something much more comfortable and reliable then this is a good opportunity.
