Antique Bee Samplera Cross Stitch Pattern by Elizabeth's Designs

Hi. This is a beautiful chart. Do you supply a DMC conversion for the floss

I am new to cross stitching and have done only a couple of patterns. My question is about the concerns of working with a small count of fabric. I have only worked with 24 count and wonder about the difficulty level of working with smaller counts such as 35 count Cornsilk Linen. Can I double the size to a larger count and still have a nice looking completed project? If doubled, as above, will I have to adjust the amount of floss? What is the difference in working with a linen and working with Aida?

I just want to confirm that I need to purchase both the fabric and floss/thread separately. That the Antique Bee Sampler only includes the pattern. Also, I see the option to add supplies to my order. Are the threads listed all the ones specifically required for this specific pattern? First time ordering, so I want to make sure I understand. Thanks.
