Hi all- New to this website, but been scrolling for about 2 years. Really it’s been in the last 6 months that I’m really starting to do more complicated cuts. I have been selling my woodwork for almost 3 years and am ready to concentrate on my scrolling and grow that side. My question, ( and struggle!), is the wood to use and where to get it. I cut a lot of words, Flowers, sports logos, etc... the wood at the big box stores (we have Home Depot and Lowe’s) don’t have the high quality MDF I need and I haven’t been able to find Baltic birch. Advice on where (online?) I can get some or another type of wood to use? I’m in Louisville. Thanks!
