I'm glad I was able to help. I have the larger Misti as at the time it was the only one around and the lady who designed it developed the smaller one later. Personally I don't believe it is necessary to have both sizes but if your budget allows for that go for it. I'm sure you know you can spend a fortune on supplies and it can be an expensive waste if you don't actually use them. I've learned to be a bit frugal and to think hard before I splurge. And you are correct in that the new Tim Holtz is a similar product. It would be worth checking out as he usually has great products and his tool may have a few extras available that the Misti doesn't. None of my acrylic blocks have grid lines and I've never found that to be a detriment. I do however use graph paper and the lines on my cutting mat to line stamps up and you can always draw the lines onto a clear block if you feel you must have them. Our inclination is to always try for perfection when crafting a card but the reality is that it is handmade and imperfections are an inherent part of that. I've learned not to fret if something is slightly off but it took me a while to let go of the need to have it all exactly right. Just recently I bled all over a challenge entry and could have cried as I didn't want to start again. Instead I got creative and managed to cover up the spots with some bling. I can laugh at myself these days but in the past I was way to serious about it. Have fun. Oh and by the way you can always write to the store and find out when the blocks are back in stock. Gina is a lovely lady and tries really hard to keep things in stock and she is very accommodating when you ask a question. I love her!
Hi Julia - the clear stamps are all different sizes so it is a good idea to have more than one size acrylic block. I have 6 different ones and a Misti as well. The acrylic blocks give you much better vision as you can see the placement before you stamp. Hope that helps.
